Triangle Sum Theorem The sum of the angle measures in a triangle equal 180 3 2 1 1 + 2 + 3 = 180 Isosceles Triangles 2 congruent sides 2 congruent base angles Isosceles Triangles & Angle Sum Theorem E + W + H = 180o W H E + 2( W) = 180o Base Angles are congruent. The formula for this theorem is pretty simple: The triangle sum theorem has varied applications and can even be extended to problems involving other polygons. All three angles have to add to 180, so we have: B + 31 + 45 = 18 0 B + 76 = 18 0 (combine like terms) B = 1 0 4 Example 2: Triangle sum theorem practice problems | Math Theorems Set up an equation like in Example 3.
