How do you find the angles of a triangle in a triangle? How To Find The Angle of a TriangleSubtract the two known angles from 180° .Plug the two angles into the formula and use algebra: a + b + c = 180° Do angles in a triangle add up to 360? Since the triangles are congruent each triangle has half as many degrees, namely 180. But if you look at the two right angles that add up to 180 degrees so the other angles, the angles of the original triangle, add up to 360 - 180 = 180 degrees....
