Q8. Find the measure of each exterior angle of a
a) regular octagon
b) regular decagon​

Answer 1

Answer:

a) regular octagon

Total measure of all exterior angle =360°

no.of sides in regular octagon = 8

Therefore, measure of each exterior angle of regular octagon (polygon)

= 360°/n

= 360°/8 = 45°

b) regular decagon

Total measure of all exterior angle = 360°

no. of sides of regular decagon = 10

Therefore, measure of each exterior angle of regular decagon (polygon)

= 360°/n

= 360°/10 = 36°
