What is the sum of the interior angles of a triangle in degrees?

Explanation:
The interior angles in any triangle add up to 180 degrees. This happens because if you draw a line parallel to one side through the opposite vertex, the other two angles become equal to the base angles, and together with the angle at that vertex they form a straight line, totaling 180 degrees. So no matter the shape, the three interior angles always sum to 180. You can test with an equilateral triangle: each angle is 60 degrees, and 60 + 60 + 60 = 180.
