two problems Geometry chapter 7, Polygons, section 7.1 The sum of the measures of the angles of a triangle is equal to 180 degrees. Definition: An exterior angle of a polygon is an angle that is adjacent to and supplementary to an interior angle of a polygon. It is formed by extending one of the sides of the polygon to the exterior. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles. Th 51 The segment joining the midpoints of two sides of a triangle is parallel to the third side and its length is onehalf the length of the third side.
