Question

find number of degrees in each exterior angle of a regular polygon?

Answer 1

Answer :

We know all internal angles of equilateral triangle = 60$°$ , So

Exterior angle of equilateral triangle = 180$°$ - 60$°$ = 120$°$

And

All internal angles of square = 90$°$ , So

Exterior angle of square = 180$°$ - 90$°$ = 90$°$

And

All internal angles of regular pentagon = 108$°$ , So

Exterior angle of square = 180$°$ - 108$°$ = 72$°$

Formula for exterior angle = $\frac{360°}{n}$ , Here n is number of sides in polygon .
