    Do you know the formula to find the sum of interior angles of a polygon? :)

    A pentagon is made up of three triangles. A triangle has 180 degrees total . . . so what do we do to solve for the total of a pentagon?

    Sum of interior angles = 180 * (n - 2) where "n" = number of sides. Note: pentagons have 5 sides.. therefore n = 5 Plug it into the formula and solve :)

    remember it is Angle sum of polygon = 180 * (n - 2) n = 5..therefore we have: angle sum of pentagon = 180 * (5 - 2)
