Question

Find the number of sides of a regular polygon whose each exterior angle has a measure of 45°

Answer 1

I m showing an easy way of finding answer of this type of questions.---

Exterior angle=360/no of sides of regular polygon

Here.given ext. Angle =45
So,
No of sides=360/45
=8 sides

Answer 2

Answer

Total measurement of all exterior angles is equal to 360 degree

Measure of each exterior angle is equal to 45 degree ==360/45=8

(therefore the number of exterior angle)

The polygon has 8 sides
