INTERIOR AND EXTERIOR ANGLES OF POLYGONS WORKSHEET - onlinemath4all In any polygon, the sum of an interior angle and its corresponding exterior angle is 180°. That is, Interior angle + Exterior Angle = 180°. 165.6° + Exterior Angle = 180°. Exterior angle = 14.4°. So, the measure of each exterior angle is 14.4°. The sum of all exterior angles of a polygon with "n" sides is. Interior and Exterior Angles Worksheets, Questions and Revision Interior and Exterior Angles The interior angles of a shape are the angles inside the shape. The exterior angles are the angles formed between a side-length and an extension. Rule: Interior and exterior angles add up to 180\degree 180°. Having the ability to rearrange equations will help with interior and exterior angle questions. Angle Sum Property and Exterior Angle Theorem | Triangle Worksheets In these pdf worksheets, the measure of one of the interior angles of each triangle is presented as an algebraic expression.
