How many vertices does a pentagon have

Pentagons can be classified into four types depending on their sides, angles, and vertices.

A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon or star pentagon is called a pentagram. The diagonals of a convex regular pentagon are in the golden ratio to its sides. Substituting the regular pentagon's values for P and r gives the formula. Similar to every regular convex polygon, the regular convex pentagon has an inscribed circle.

With this pentagon calculator, you'll find essential properties of a regular pentagon : side, diagonal, height, perimeter, and area, as well as the circumcircle and incircle radius. Type any value, and the remaining parameters will be calculated on the spot. If you are not sure what a pentagon is or how many sides a pentagon has, keep scrolling, and you'll find clarifying pictures with a short explanation. A regular simple pentagon has all five sides equal in length. In this article, we use the term "regular pentagon" to describe a regular simple pentagon.
