Pentagon | |
---|---|
An equilateral pentagon, i.e. a pentagon whose five sides all have the same length | |
Edges and vertices | 5 |
Internal angle (degrees) | 108° (if equiangular, including regular) |
What is the size of an interior angle of a regular 5 sided polygon?
The General Rule
If it is a Regular Polygon (all sides are equal, all angles are equal) | ||
Shape | Sides | Each Angle |
---|---|---|
Triangle | 3 | 60° |
Quadrilateral | 4 | 90° |
Pentagon | 5 | 108° |
How do you find the measure of an interior angle in a regular polygon?
Let’s recap. A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n – 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n – 2) * 180 / n.
What are the interior angles of a regular polygon?
The interior angles of a polygon are equal to a number of sides. Angles are generally measured using degrees or radians. So, if a polygon has 4 sides, then it has four angles as well….Interior angles of Regular Polygons.
