Use the given paragraph proof to write a two-column proof. Given: Triangle XYZ is a right triangle. ÐZ is a right angle. Prove: ÐX and ÐY are complementary angles. Triangle XYZ is a right triangle, and ÐZ is a right angle. So, mÐZ = 90° by the definition of a right angle. By the Triangle Sum Theorem, mÐX + mÐY + mÐZ = 180°. By the Subtraction Property of Equality, mÐX + mÐY + mÐZ – mÐZ = 180° – mÐZ. So, mÐX + mÐY = 90°. Therefore, ÐX and ÐY are complementary angles by the definition of complementary angles.
