Interior and exterior angles of polygons practice

The sum of the exterior angles of a polygon is 180 ( n – 2), where n represents the number of sides. The sum of the angles of a pentagon (five sides) is equal to. The pentagon is missing one interior angle, which you can call y: The interior and exterior angles of a polygon are supplementary. Therefore, 20 degrees.

Unit 5 - Polygons & Area Investigate patterns to make conjectures about geometric relationships including diagonals in quadrilaterals and interior and exterior angles of polygons. Verify theorems about the sum of interior angles and exterior angles and apply these relationships to solve problems The interior angles of any polygon always add up to a constant value, which depends only on the number of sides. For example the interior angles of a pentagon always add up to 540° no matter if it regular or irregular, convex or concave , or what size and shape it is.
