The measure of an exterior angle of an equiangular polygon is twice that of an interior angle. What is the name of the polygon?

Answer 1

exterior angle of a polygon with n sides is 360/n
inside angle is 180(n-2)/n

so 360/n = 2(180)(n-2)/n
360 = 360n - 720
360n = 1080
n = 3

looks like an equilateral triangle

check: inside angle = 60 degrees
exterior angle is 120 degrees
