Learn three types of angle pairs: vertical angles, complementary angles, and supplementary angles.
The naming of an angle is related to the line segments that create it. We'll also learn about the angle's vertex. Come on. Let's do this.
Name angles by their vertex, endpoints, or labels.
Practice telling whether two angles are supplementary, complementary, or vertical.
Let's add some tools to our geometry tool belt. Here's a thorough explanation of complementary and supplementary angles, as well as definitions of adjacent and straight angles.
By using our knowledge of supplementary, adjacent, and vertical angles, we can solve problems involving the intersection of two lines. Including this one!
