This lesson provides practice problems that apply the triangle exterior angles theorem. </p> The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent. Start with the following isosceles triangle. The two equal sides are shown with one red mark and the angles opposites to these sides are also shown in red An exterior angle of a triangle is equal to a sum of interior angles, not supplementary with it: BCD = A + B. 5. Any side of a triangle is less than a sum of two other sides and more than their difference ( a < b + c, a > b - c; b < a + c, b > a - c; c < a + b, c > a - b ).
