Supplementary angle theorems5/6/2023 An ‘angle’ is the measurement of the ‘opening’ between these two rays. Definition of anglesĪngles are created when two lines meet at a single point. For instance, if two angles measure 110° and 70°, they can be considered complementary angles because their sum equals 180°. By combining complementary angles together, right angles can be produced. When the total of two angles equals exactly 180°, they are referred to as supplementary angles. For instance, two angles measuring 65° and 25° are complementary since their sum is exactly 90°. When two complementary angles are adjacent, a right angle is created. Supplementary angles can easily be understood with the help of online worksheets and courses that make it very interesting for students to understand and grasp.The primary distinction between a complementary angle and a supplementary angle is that the sum of the two angles that comprise a complementary angle is 90°, but the total of the two angles that comprise a supplementary angle is 180°.Ĭomplementary angles are generated when the total of two angles equals precisely 90 °. The world of the internet has made everything very easy and accessible for students. Supplementary angles can also be very confusing for children. Supplementary and are very important concepts in mathematics and geometry. The supplementary angle theorem states and explains that if any two given angles are supplementary to the same angle, then the two angles are proved to be congruent.
