Answer #1

We know that the sum of all interior angles of a regular n-gon is

Therefore, measure of each interior angle of a regular n-gon is

Hence, the measurements of all interior angles of a regular decagon (n = 10) is

We know that the sum of all exterior angles of a regular n-gon is

Therefore, measure of each exterior angle of a regular n-gon is

Hence, the measurements of all exterior angles of a regular decagon (n = 10) is
