Vertical, Complementary and Supplementary Angles

In this math video we will identify and use facts about vertical, complementary & supplementary angles to solve problems. We will review the definition of an angle. We will draw an angle from two rays and a vertex. We will draw intersecting lines that meet at a vertex and form angles. We will understand that vertical angles are formed by intersecting lines. Vertical angles are opposite each other, share a common vertex and are congruent. We will learn that complementary angles are two angles whose sum is 90 degrees. We will learn that complementary angles could be two angles that are adjacent angles. We will learn that supplementary angles are two angles whose sum is 180 degrees. Student practice problems are throughout the lesson. Exemplar solutions are modeled and explained.
