You can put this solution on YOUR website! The interior angles of a regular polygon measure 160° each. The numbers of diagonals of the polygon are
----
Each exterior angle is 20 degrees.
---
# of exterior angles = 360/20 = 18
---
# of sides = # of vertices = 18
----
# of pairs of vertices = 18C2 = 153
----
# of diagonals = 153-18 = 135
