Key takeaways
Have you ever stared at a beehive and thought, “Wow, those shapes are really cool!”? What you’ve actually been looking at are natural hexagons – six-sided polygons that fit together perfectly!
So what is a hexagon, and how can we measure its perimeter, area, and more? Let’s take a closer look at this unique shape
A hexagon is a six-sided polygon with six interior angles. There are two different types of hexagons – regular and irregular hexagons.
To be considered “regular,” a hexagon must have six equal sides and six angles that each measure 120°.
So where does the word “hexagon” come from? Well, the prefix “hexa” means six, and “gonia” means angles. Put that together, and you get “six angles,” a requirement for a shape to be called a hexagon!
Hexagons are some of the most naturally occurring shapes in the world! That’s because six sides tend to fit together perfectly to make a strong, dynamic shape or design. You’ll see hexagons when you study beehives, insect eyes, and the center of snowflakes.
Ever kicked a soccer ball around? The black and white designs that make up the outside of the ball are hexagons! They are also a popular choice for tile floors, given they fit so neatly together.
Fortunately, hexagons don’t have as many rules to follow as, say, a square, a rectangle, or a triangle.
Basically, a hexagon has:
See the major pattern here? Six, six, six! However, there are different types of hexagons, and each of them have their own set of rules. Let’s take a look at these different types together.
Regular hexagons follow more rules than other types of hexagons. In order to be considered a regular hexagon, the shape must have:
If you’re calculating the perimeter of a regular hexagon, you simply need to multiply the length of one side by 6 to get the perimeter of the entire shape.
Some other fun facts about a regular hexagon:
Every regular hexagon will also be a convex hexagon. When something is convex, it means that it only has interior angles. In a regular hexagon, all angles must be interior, so a regular hexagon is also a convex hexagon.
When we think about the word irregular, we think about “strange” or a little whacky, right? Think about irregular hexagons in the same way. They still have to have six sides, and they must be a closed shape, but outside of that, they get to break the rules.
The word “concave” literally has the word “cave” in it, right? In a concave hexagon, at least one of the angles will be an exterior angle, which may make the shape look like it has a mouth!
Concave hexagons still have to have – you guessed it – six sides! But two of those sides will likely point inward rather than creating a smooth, round perimeter.
Shapes like circles and squares have specific formulas for measuring area and perimeter. There is a formula to measure the area of a hexagon, but you likely will not need it until much later in your academic career.
We are going to focus on the measurement you’ll likely need to calculate once you start working with hexagons: perimeter.
You probably know that the perimeter of any shape is the measure of its exterior sides. To calculate the perimeter of a hexagon, simply add up each of the shape’s sides.
For a regular hexagon, you can do this pretty easily. Simply use the measurement of one side, then multiply that number by 6.
For an irregular hexagon, you will want to add up each of the sides on your own.
The correct answer is A. A is the only hexagon that has 6 equal sides and 6 equal angles. Both B and C are irregular hexagons.
The answer is FALSE. Figure C is actually a concave hexagon, while Figures A and B are convex hexagons. See how Figure C has a piece that looks like a cave or a mouth? That’s how you can tell!
Since we’re calculating the perimeter of a regular hexagon, we know that we can multiply one side by 6 to get the perimeter.
So, 7 × 6 = 42 inches.
Ready to give it a go?
It’s time to put your knowledge of hexagons to the ultimate test! Work through the following problems on your own. Feel free to look back at the practice problems above if you get stuck, or use the guide to refresh your memory.
And remember, don’t get discouraged if you run into a roadblock! Practice is the best way to learn something new.

Since concave hexagons include at least one exterior angle, they cannot be regular hexagons, which must have 6 interior angles that measure 120°.

No, not all six-sided shapes are called hexagons. A hexagon is a specific type of six-sided shape with straight sides. It has six angles and six sides that are all equal in length. Each side of a hexagon connects to two other sides, and it has a total of six corners, which are called vertices.
No, not all hexagons have equal sides. A hexagon is a polygon with six sides, but its sides can have different lengths. A hexagon with equal sides is called a regular hexagon. In a regular hexagon, all six sides are the same length, and all six angles are equal.
The hexagon is often considered a strong shape because it distributes forces or weight evenly across its sides. This means that when you push or pull on a hexagon, the pressure or force is spread out more evenly compared to other shapes.
