Question

Find the measure of each exterior angle of a regular polygon if the interior angle is 60 degree .Also name the polygon

Answer 1

Exterior Angle = 90 - Interior Angle

Therefore.. Extr. = 90 - 60

Extr. Angle = 30 degrees

Number of Sides = 360/ Exterior Angle

Therefore... 360 /30 = 12 sides

Which is called a dodecagon.
