In the picture below, the angles â ABC, â BCA and â CAB are the three interior angles of the triangle. An exterior angle is formed by extending one of the sides of the triangle; the angle between the extended side and the other side is the exterior angle. In the picture, angle â ACD is an exterior angle. Euclid's exterior angle theorem
the sum interior Si of the measures of the angles of a polygon with n sides is given by the formula Si=(n-2)180 exterior angle sum if 1 exterior angle is taken at each vertex, the sum exterior(Se) of the measures of the exterior angles of a polygon is given by the formula (Se)=360 the number (d) of diagonals that can be drawn in a polygon of n sides is given by what formula
