Definition

An exterior angle is an angle formed outside a polygon by extending one of its sides.

Description

Exterior angles are used in the study of polygons, where the sum of the exterior angles of a polygon is always 360 degrees. They are essential in solving problems involving polygon properties and in understanding the relationships between interior and exterior angles. In real-world applications, exterior angles are used in design and architecture to create aesthetically pleasing and functional structures. For students, learning about exterior angles enhances their understanding of polygon geometry and helps develop skills in geometric reasoning and problem-solving.
