Written by theFigure 4.1.1 4.1. 1. The sum of the interior angles in a triangle is 180∘ 180 ∘. This is called the Triangle Sum Theorem and is discussed further in the "Triangle Sum Theorem" concept. Angles can be classified by their size as acute, obtuse or right. In any triangle, two of the angles will always be acute.5-5 Study Guide and Intervention Inequalities in One Triangle Angle-Side Relationships When the sides of triangles are not congruent, there is a relationship between the sides and angles of the triangles. o If one side of a triangle is longer than another side, then the If AC > AB, then mZB > mZC.
