WebSep 1, 2024 · For each triangle, there is a right angle. This is the angle opposite to the hypoteneuse. Now, notice that each of the other two angles are just 90° split in half. Thus, we now have a right angle and two 45° angles. 90° + 45° + 45° = 180°. Thus, the sum of all angles of a triangle is 180°. Hope this helps!
