An interior angle of a triangle is formed by two sides of the triangle. an exterior angle is formed by one side of the triangle and the extension of an adjacent side. each exterior angle has two remote interior angles. a remote interior angle is an interior angle that is not adjacent to the exterior angle. We just proved in solution 2 an important theorem in geometry called the exterior angle theorem. you can use this theorem in solving many geometry problems involving triangles and other polygons. exterior angle theorem states that in a triangle, the measure of an exterior angle is equal to the sum of the two remote interior angles. In order to understand the exterior angle theorem, its important that you know about remote interior angles. remember, interior angles are on the inside of a triangle. each exterior angle has 2 remote interior angles. the remote interior angles are the two angles on the inside of the triangle that are not touching the exterior angle.
See more videos for remote interior angles problems. How to solve for the measure of an exterior angle when the values of the interior angles are given in terms of variables. video explanation and sample problems. Since x and, $$ \angle j $$ are remote interior angles in relation to remote interior angles problems the 120 angle, you can use the formula. $$ 120 = 45 + x \\ 120 45 = x \\ 75 = x. $$ now, since the sum of all interior angles of a triangle is 180. you can solve for y.
