Question

20. Find the measure of each interior angle AND each exterior angles of the following regular polygons. Show your work.

a. Pentagon


b. 16-gon


c. Dodecagon

Answer 1

pentagon has 5 angles. 360/5= 72 degrees
16-gon has 16 angles. 360/16= 22.5 degrees
dodecagon has 12 angles. 360/12= 30 degrees
The measure of the exterior angle of any regular polygon is 360 divides by the number of sides the polygon has.
