WebTriangles are polygons with three sides and three angles. They are classified by their angles as well as by their sides. Like other polygons, triangles have two sets of angles: interior angles and exterior angles. Specifically, a triangle’s interior angles always add up to 180°, and the exterior angles add up to 360°.

WebThe angles in the triangle add up to 180 degrees. So a + b + y = 180. The angles on a straight line add up to 180 degrees. So x + y = 180. Therefore y = 180 - x. Putting this into the first equation gives us: a + b + 180 - x = 180. Therefore a + b = x after rearranging.
