How many triangles are formed by drawing diagonals from one vertex in the polygon?What is the sum of the measures of the angles in the polygon?
180(n-2) = sum of the measures of the interior angles.
(n-2) = number of triangles, where n = number of sides
(10 - 2) = 8
180(10-2) = 1440
180(n-2) = sum of the measures of the interior angles.
(n-2) = number of triangles, where n = number of sides
(12 - 2) = 10
180(12-2) = 1800
