Question

The polygon Angle-Sum Theorem states the following: The sum of the measures of the angles of an n-gon is_____.

Answer 1

Answer: 180*(n-2)

You can write it as 180(n-2)

-------------------------------------------

For example, if n = 4, then 180(n-2) = 180*(4-2) = 360 meaning that the angles of a quadrilateral add to 360 degrees.
