Lesson: 1: Lines and Angles
Topic: Pairs of Angles
Domain: Geometry

Seven names, three facts: a straight line is 180, a full turn is 360, and parallel lines slide an angle along unchanged.

Study Tip

Before using corresponding, alternate or co-interior, look for the arrow marks. No marks means the lines are not given as parallel, and none of those three may be used.
