For example: Consider the following polygon with 5 sides, So, each interior angles = (n 2) 180n. Less commonly, a simple algorithm is used to add geometry to a mesh by subdividing the faces into smaller ones without changing the overall shape or volume. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons.
