Have you ever looked at a shape with 7 sides and wondered what it’s called? Well, wonder no more! In this article, we’ll explain all about 7 sided shapes, including their name, properties, and some fun examples.
So, what is a 7 sided shape called? The answer is a heptagon. The word heptagon comes from the Greek words “hepta,” which means seven, and “gonia,” which means angle. A heptagon is also sometimes called a septagon.
What are the properties of a heptagon? Here are a few key facts:
- A heptagon has 7 sides and 7 angles.
- All of the angles in a heptagon add up to 900 degrees.
- A regular heptagon has equal side lengths and equal angles.
- The formula for finding the measure of each angle in a regular heptagon is: (7-2) x 180 / 7 = 128.57 degrees.
Heptagons can be found in many real-world objects. For example, some coins such as the British 50 pence coin have the shape of a heptagon! Can you think of any other objects that might have a heptagon shape?
Now that you know all about heptagons, you might be curious about other shapes with different numbers of sides. Here are a few more shapes and their names:
- 3 sides: triangle
- 4 sides: quadrilateral
- 5 sides: pentagon
- 6 sides: hexagon
- 8 sides: octagon
- 9 sides: nonagon
- 10 sides: decagon
Learning about shapes and their properties is an important part of math. We hope this article helped you learn all about heptagons and other shapes. Keep exploring and discovering new things in the world of math!
