Corollary to the Triangle Sum Theorem: The acute angles of a right triangle are complementary. m ∠ ∠ A and m ∠ ∠ C are complementary so m ∠ A + m ∠ C = 90°. ∠ A When you're dealing with triangles, the Triangle Sum theorem can be very useful in finding interior angle measurements. In this tutorial, learn how to find this helpful theorem!
