Find total number of sides of a regular polygon whose each exertion angle has a measure of 45o.
Total measure of ext. angles =360∘Measure of each =45∘NO. of sides =360/∘45∘=8∴ there are 8 sides.
Each interior angle of a regular polygon is 144°. The measure of each interior angle of a regular polygon which has double the number of sides as the first polygon is
