Figure 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.2) Cut out enough triangle shapes for each student. 3) Post a sign that says "Congruent" and one that says "Not Congruent" on opposite sides of the classroom. 4) Open PowerPoint labeled "Congruence and Triangles."
