+ Angle Relationships in Triangles Geometry Farris 2015 + I can find the measure of and apply the theorems about interior and exterior angles of triangles. + Theorem 4-3-1 Triangle Sum Theorem The sum of the angles measures of a triangle is 180 degrees. + + Corollary - A theorem whose proof follows directly from another theorem. + + 3 2 1 Angle Z is an exterior angle. Its remote interior angles are angles 2 and 3. + 4-3-4 Exterior Angle Theorem The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles. + + 4-3-5 Third Angles Theorem +
