Triangle Exterior Angle Worksheet Answer Key
Triangle Exterior Angle Worksheet Answer Key - The exterior angle theorem worksheet helps the students solve unknown angles to find the interior and exterior angles of a triangle. For example, in problem 1, the exterior angle (x) is congruent to the sum of the two angles furthest away. Mathematically, if you have a triangle with interior angles ∠a, ∠b, and ∠c, and an exterior angle at one of its vertices, say ∠d, the exterior angle theorem can be expressed as: The measure of an exterior angle of a triangle is equal to sum of the measures of opposite interior angles.
