👉 Learn how to determine the measure of the interior angles of a regular polygon. A polygon is a plane shape bounded by a ...

Polygons can be regular or irregular in shape. A polygon is a closed 2D shape with at least three sides. A regular polygon is a polygon with all equal sides and angles. An irregular polygon is a ...

The sum of the angles inside any polygon can be found by spitting the polygon into triangles. Sum of interior angles = 180(n – 2) where n is the number of sides In a regular polygon all the angles are ...

👉 Learn how to solve for an unknown variable in the exterior angle of a polygon. The exterior angle of a polygon is the angle between a side of the polygon and an outward extension of the adjacent ...

Before reading this guide, it may be helpful to read the guides from Module 1 on the properties of angles and the properties of 2D shapes. The sum of the angles inside any polygon can be found by ...
