Question

What is the sum of all the angles of an equiangular hexagon if each angle measures 120°

Answer 1

The general formula to find the sum of interior angles of any polygon is: 

180(n-2)

 where n is the number of side of the polygon.

Since an equingualar hexagon has 6 sides,and each angle measures $120\degree$ then the sum of all interior angles is:

$(120\degree × 6)=720\degree$
