This unit covers many different types of angles such as vertical angles, supplementary angles, and complementary angles, all of which will be seen in later units. This unit also covers transversal lines and the angles created by transversal lines, auxiliary lines, and angles in a triangle.
The picture above displays a vertical angles problem, a transversal line, and an isosceles triangle problem.
