In this post, we'll take a closer look at a regular hexagon - a six-sided polygon where all the sides are equal. We will look at its angles, and find formulas for its perimeter and area using its side … [Read more...] about Regular Hexagon

# Pentagons and Hexagons

Pentagons are polygons with 5 sides. The sum of the interior angles in a pentagon is 540°.

In a regular pentagon, all the sides and all the angles are equal, and so each of the interior angles measures 540°/5= 108°.

Similarly, hexagons are polygons with six sides. The sum of the interior angles in a hexagon is 720°.

In a regular hexagon, all the sides and all the angles are equal, and so each of the interior angles measures 720°/6= 120°.

*Now that we've explained the basic concepts of pentagons and hexagons in geometry, let's scroll down to work on specific geometry problems relating to this topic.*

## Sum of Angles in a Pentagon

In today's geometry lesson, we will show that the sum of the interior angles in a pentagon is 540°. And then we will generalize the proof to get a formula that can be used to find the sum of all … [Read more...] about Sum of Angles in a Pentagon
