What Is The Name Of A Polygon With 6 Sides? | One Word Answer

A polygon with six sides is called a hexagon.

If you’re staring at a six-sided shape and trying to name it, the answer is simple: it’s a hexagon. That’s the standard math term, and it works whether the sides all match or not. Once you know that one word, a lot of other geometry terms start to click into place.

This shape shows up early in school math, yet it doesn’t stay there. Hexagons appear in floor tiles, bolts, game boards, logos, and honeycomb patterns. So this isn’t just a vocabulary item to memorize and forget. It’s a shape name you’ll keep running into.

There’s also a neat reason the word sounds the way it does. “Hexa” means six, and “gon” means angle. Put them together and you get the name for a six-angled, six-sided polygon. Once that pattern sinks in, names like pentagon and octagon start making more sense too.

What Is The Name Of A Polygon With 6 Sides? In Plain Math

In plain math, a six-sided polygon is a hexagon. A polygon is a closed flat shape made with straight line segments. So to count as a hexagon, the figure must meet three basic checks: it must be flat, closed, and built from six straight sides.

That “closed” part matters. If the lines don’t meet all the way around, it isn’t a polygon yet. Curved edges don’t count either. A shape with six curved edges may look close, but it isn’t a hexagon in geometry.

The six sides also create six angles. That’s why the shape name tracks both side count and angle count. In school problems, teachers may ask for the number of sides, the number of vertices, or the number of interior angles. For a hexagon, all three counts are six.

Why The Word Hexagon Fits So Well

Math words can feel stiff when you first meet them. Hexagon is one of the friendlier ones because the pieces of the word tell you what it means. “Hexa” points to six. “Gon” points to angles. So the name itself gives away the count.

That pattern helps with shape names across geometry. A triangle has three sides. A quadrilateral has four. A pentagon has five. A hexagon has six. An octagon has eight. Once you spot the number pattern, shape names stop feeling random.

You don’t need Greek roots memorized to use the word well. Still, knowing the pattern makes shape names easier to recall under pressure. If you’re in class, doing homework, or helping a child study, that little bit of word logic saves time.

Hexagon Vs. Regular Hexagon

This is where many people get tripped up. Every regular hexagon is a hexagon, but not every hexagon is regular. “Hexagon” only tells you the shape has six sides. “Regular hexagon” tells you more: all six sides are equal, and all six interior angles are equal too.

That difference matters in geometry questions. A sketch with six sides of mixed lengths is still a hexagon. It just isn’t a regular one. If all sides match and the corners match, then you can call it a regular hexagon.

In a regular hexagon, each interior angle is 120 degrees. That number shows up often in classwork. A non-regular hexagon can still be valid, yet its angles may differ from one corner to the next.

What A Hexagon Must Have

If you want a fast way to test a shape, use this short checklist:

• It has six straight sides.
• It is closed with no gaps.
• It lies flat on a plane.
• It has six vertices.
• It has six interior angles.

If one of those parts is missing, the shape needs a different name. A figure with six sides and one curved edge isn’t a polygon. A figure with six straight segments that never closes also misses the mark.

Counting Sides The Right Way

When people miss this question, they usually count too fast. They may count corners instead of sides, or they may skip a tiny edge in an uneven drawing. The safest move is to pick one side, trace around the shape, and count each straight segment once.

It also helps to mark the vertices as you go. Start at one corner and label the points A, B, C, D, E, and F. If you land back where you started after six segments, you’ve got a hexagon.

For hand-drawn figures, don’t let symmetry fool you. Some sketches look like a pentagon at first glance, then you spot one more edge tucked into the top or side. Slow counting beats quick guessing every time.

Six-Sided Polygon Names And Terms That Matter

By this point, the answer is clear. Still, a few related terms help the full picture stick. The table below lays out the pieces students most often need when the shape comes up in class.

Term	What It Means	How It Applies To A Hexagon
Polygon	A closed flat figure made from straight sides	A hexagon is one kind of polygon
Hexagon	A polygon with six sides and six angles	This is the full name of the shape
Regular Hexagon	A hexagon with equal sides and equal angles	Each interior angle is 120°
Irregular Hexagon	A hexagon with sides or angles that do not all match	Still a hexagon if it has six straight sides
Side	A straight edge of the shape	A hexagon has 6 sides
Vertex	A corner where two sides meet	A hexagon has 6 vertices
Interior Angle	An angle inside the shape	The angle sum is 720°
Perimeter	The total distance around the shape	Add all 6 side lengths
Diagonal	A line joining nonadjacent vertices	A hexagon has 9 diagonals

That angle sum of 720 degrees often shows up in worksheets. You can get it from the polygon angle rule: subtract 2 from the number of sides, then multiply by 180. For six sides, that gives (6 − 2) × 180 = 720.

If you want a dictionary-style definition, Merriam-Webster’s definition of hexagon states that a hexagon is a polygon of six angles and six sides. That wording matches what schools teach.

How A Hexagon Compares With Nearby Shapes

Students don’t usually confuse a hexagon with a triangle. The mix-up happens with shapes that sit close by in the counting order, like pentagons and heptagons. So it helps to place the hexagon in the middle of the sequence.

A pentagon has five sides. A hexagon has six. A heptagon has seven. That one-step shift matters. If you count carelessly, you can slide into the wrong label without noticing.

There’s also a visual clue. A regular hexagon often looks balanced and broad, almost like a circle built from straight lines. A regular pentagon feels tighter. A heptagon looks a little rounder because it has one more side.

Common Shape Mix-Ups

One common mix-up is between a hexagon and an octagon. Stop signs make the octagon famous, so some people start using that word too freely. An octagon has eight sides, not six. If the drawing has six edges, octagon is out.

Another mix-up happens with 3D objects. A nut or bolt head may look hexagonal from one view, yet the full object is not a flat polygon. The face can be a hexagon, while the whole item is a solid figure.

If you’re working from a photo or object, ask one clean question: am I naming the flat face, or the full object? That clears up a lot.

Where You’ll See Hexagons In Real Life

Hexagons turn up more often than most people think. Honeycomb cells are the classic case. Board games use hex grids because they pack neatly while giving each tile many neighbors. Bathroom tiles, pencils, and bolt heads also bring the shape into daily life.

Math classes like hexagons for another reason: regular hexagons tile a flat surface without gaps. Squares do this too, yet hexagons create a different pattern and often use space neatly. That makes them useful in design and mapping.

Britannica’s page on the shape notes that a hexagon is a six-sided polygon and adds that regular hexagons pack a plane with no wasted space. You can read that in Britannica’s hexagon entry, which also gives the regular-hexagon angle and area facts.

Shape	Number Of Sides	Name To Use
5-sided polygon	5	Pentagon
6-sided polygon	6	Hexagon
7-sided polygon	7	Heptagon
8-sided polygon	8	Octagon

A Fast Way To Remember The Answer

If shape names slip out of your head during a test, use a memory hook. “Hex” lines up with six in a lot of number-based terms. So when you hear hexagon, tie it to six right away.

You can also pair the word with a mental picture of a honeycomb cell. That image sticks for many learners because it’s concrete and easy to recall. Then when the question pops up again, the name comes back with the picture.

Another easy trick is to say the shape family in order: triangle, quadrilateral, pentagon, hexagon, heptagon, octagon. Running the sequence a few times builds the count pattern into memory.

What Teachers Usually Want In This Question

Most of the time, the teacher isn’t testing hard geometry here. They’re checking whether you know the standard shape name and whether you can connect side count to vocabulary. So the clean answer should be short and direct: a polygon with six sides is a hexagon.

If the task asks for more detail, you can add that it has six vertices and that a regular hexagon has equal sides and equal angles. That’s often enough to show full understanding without drifting off-topic.

When the question appears in multiple-choice form, scan the options by side count. Pentagon means five, hexagon means six, octagon means eight. If you know those anchors, the answer stands out fast.

The Answer, Kept Simple

The name of a polygon with six sides is hexagon. That’s the whole answer, and it stays true whether the shape is regular or irregular. If it has six straight sides and closes fully, hexagon is the right word.

Once that part is locked in, the rest of the geometry around it gets easier. You can sort nearby shape names, count angles with more confidence, and spot the form in class diagrams and real objects without second-guessing yourself.
