Instructions: In this worksheet, you will explore the properties of angles formed when parallel lines are cut by a transversal. Read each section carefully and complete the exercises that follow.
1. Introduction to Parallel Lines and a Transversal
When two parallel lines are intersected by a third line (called a transversal), several pairs of angles are formed. The important angle relationships to remember are:
– Corresponding Angles: Angles that are in the same position relative to the parallel lines and the transversal.
– Alternate Interior Angles: Angles that are on opposite sides of the transversal and inside the parallel lines.
– Alternate Exterior Angles: Angles that are on opposite sides of the transversal and outside the parallel lines.
– Consecutive Interior Angles (Same-Side Interior Angles): Angles that are on the same side of the transversal and inside the parallel lines.
