Heptagon

Pro Tip 1/3

Heptagon is specifically used in geometry to discuss shapes with seven sides.

In geometry class, we learned how to calculate the area of a heptagon.

Pro Tip 2/3

A common mistake is to think stop signs are heptagons; they are actually octagons.

I corrected my friend when she mistook the octagonal stop sign for a heptagon.

Pro Tip 3/3

Heptagons are less common in daily life than other shapes like triangles or squares.

While playing a game, we had to think hard to find a heptagon-shaped object.
