What is an exterior angle of a polygon?

Options

• An angle formed inside the polygon between two adjacent sides

• An angle that forms a linear pair with an interior angle by extending a side of the polygon

• The angle between two adjacent exterior angles

• An angle greater than 180 degrees

Answer 1

An angle that forms a linear pair with an interior angle by extending a side of the polygon

Explanation:

Exterior angles are formed by extending the sides of a polygon. Each exterior angle forms a linear pair with the corresponding interior angle on a straight line.
