Question

if an exterior angle of a regular polygon is equal to its and interior angle find the number of sides

Answer 1

heya!!! see the pic for ur ans
tips
know the formulas of polygons for external and internal angles

alternative way
we know that
exterior angle +interior angle =180
as per question
exterior angle =interior angle =x
this implies
x+x=180
2x=180
x=90

so each exterior angle=90°
number of sides =360°/exterior angle
=360/90=4

Ans 4 sided polygon
