The Exterior Angle Theorem says that an exterior angle of a triangle is equal to the sum of the 2 non adjacent interior angles Taking our above example ACD ACD would equal whatever A A B B equaled because those are the two angles NOT connected to the exterior angle Let s try two fairly basic examples and then try a Math explained in easy language plus puzzles games quizzes worksheets and a forum For K 12 kids teachers and parents Exterior Angle Theorem The exterior angle d of a triangle equals the angles a plus b is greater than angle a and is greater than angle b Example
Directions Find the measurement of each missing angle in the triangles below Remember the Exterior Angles Theorem states that the exterior angle is congruent to the sum of the two non adjacent angles For example in Problem 1 the exterior angle x is congruent to the sum of the two angles furthest away 60 80 The measure of an exterior angle of a triangle is equal to sum of the measures of opposite interior angles Exterior angle ACX Opposite interior angles Exterior angle Sum of opposite interior angles 80 2 25 4 5 6 30 B C A X 80 2 4 5 50 50 5 Triangle Exterior Angle MS2
