Question

What is something special about the relationship between an interior and exterior angle that are adjacent?

Answer 1

Explanation:

Interior angle is formed by two sides of a polygon. The corresponding exterior angle is formed by one of these sides and continuation of another (see the drawing.) That makes these two angles adjacent to each other and together forming a straight angle of 180o degree.

I hope this helps a bunch! Make sure to rephrase!

Answer 2

Hi Elm!

Explanation:

In a polygon, the sum of the measures of the interior angles and the sum of the measures of the exterior angles of adjacent angles are related. Specifically, the sum of the measures of the interior angles of a polygon is equal to (n - 2) times 180 degrees, where n is the number of sides in the polygon. For a given interior angle and its adjacent exterior angle, the measure of the exterior angle is equal to the sum of the interior angle and 180 degrees.
