The Sum of the Angles in a Triangle. Introduction: The sum of the angles in a triangle is 180Âº. We show why that is true and give several examples. The Lesson: In the diagram shown above, we see triangle ABC and the dotted line through A that is parallel to BC. Since angle A, from the triangle, and angles 1 and 2 form a straight (dotted) line, the sum of their measures is 180Âº.
