Angles in a triangle sum to 180° proof
The sum of the interior angle measures of a triangle always adds up to 180;. We can draw a line parallel to the base of any triangle through its third vertex. Then we use transversals, vertical angles, and corresponding angles to rearrange those angle measures into a straight line, proving that they must add up to 180.
