Corresponding Angles

Author:Taylor Burnett
Topic:Angles
In this workbook we will investigate the relationship between angles that are formed when a line intersects two parallel lines. For each task below, use the applets to help you answer the corresponding questions.

PART 1

In the below applet, the two lines are parallel. Move the points on the lines to investigate what it means for two lines to be parallel, and then answer the questions that follow.

In your own words, describe what we mean by parallel lines?

PART 2

In the below applet, two parallel lines are intersected by a third line (known as a transversal line). Some angles are therefore formed, use the applet to investigate these angles.

What do you notice about the blue angles?

What do you notice about the red angles?

The pair of blue and red angles are what we call corresponding angles. Corresponding angles are always equal. The brown angle is not corresponding with the blue angles. Although they are equal, they lie on different sides of the intersecting line.

In your own words, describe what it means for two angles to be corresponding.
