What is the ratio of the measure of an interior angle to the measure of an exterior angle in a regular hexagon? A regular decagon? A regular n-gon?
Let's do the last one first:
The sum of the interior angles of any n-gon is given by
If the polygon is regular then all of its interior angles are equal in
measure, so each one of them must be that sum divided by n. So
The sum of the exterior angles of any n-gon is 360°
If the polygon is regular then all of its exterior angles are equal in
measure, so each one of them must be 360° divided by n. So
So the ratio of the measure of an interior angle to the measure of an
exterior angle in a regular n-gon is
Invert the second fraction and change division to multiplication
Cnacel the n's and the 180° into the 360° getting 2 on the bottom:
A regular hexagon has 6 sides, so substitute n=6 in the equation:
and the ratio is 2 to 1 or 2:1.
A regular decagon has 10 sides, so substitute n=10 in the equation:
and the ratio is 4 to 1 or 4:1.
