In the polygon there are as many vertices as there are sides. The triangle has 3 sides and 3 vertices. The quadrilateral has 4 sides and 4 vertices. The pentagon has 5 sides and 5 vertices.

What are the different types of pentagons?

Types of Pentagons

  • Regular or equilateral pentagon: five equal sides and angles.
  • Irregular pentagon: five unequal sides and unequal angles.
  • Convex pentagon: no internal angle can be greater than 180 degrees.
  • Concave pentagon: has an internal angle greater than 180 degrees causing two sides to “sink in” like a “cave”

Why is the Pentagon 5 sides?
