WebTriangles Contain 180° In a triangle, the three interior angles always add to 180°: A + B + C = 180° Try it yourself (drag the points): We can use that fact to find a missing angle in a triangle: Example: Find the Missing Angle "C" Start With: A + B + C = 180° Fill in what we know: 38° + 85° + C = 180° Rearrange C = 180° − 38° − 85° Web32. There is always the "taxicab" proof. Start at a vertex and take a cab trip around the triangle. The cab will have turned through an angle of 360 o Extend the sides of the triangle appropriately and you will get three 180 o angles with the vertex angles being supplementary to the turns taken by the cab.
