    Interior and Exterior Angles in Polygons — Practice Geometry Questions By Allen Ma, Amber Kuang In geometry, you can find the sum of the interior or exterior angles of a polygon based on the number of sides the polygon has. You can then apply this information to find individual interior or exterior angles.

    Here is what we know about exterior angles and polygons: 1. A polygon with n sides will have n interior angles and n exterior angles (one at each vertex). 2. By its formation, an exterior angle is supplementary to its adjacent interior angle. 3. At each vertex of the polygon, the interior angle and the exterior angle form a linear pair.

x + y + z = 180 (this is the first equation) w + z = 180 (this is the second equation) Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation: x + y + (180 - w) = 180. x + y - w = 0. x + y = w. Interesting. This tells us that the measure of the exterior angle equals the total of the other two interior angles.
