Types of Angles Created by Two Parallel Lines Cut by a Transversal

Check the boxes to see different types of angles created when two parallel lines are cut by a transversal.

## In this investigation, you’ll discover relationships among the angles formed when two parallel lines are intersected by a third line, called a transversal.

Use the applet to help you answer the following questions. You must answer these questions on BGD = __________ m FHG = ___________
AGH = _________ m GHC = ___________
GHC = _________ m HGB = ___________
BGD = _________ m CHE = ___________
3. Based on your observations, fill in the blank for each statement:
Corresponding angles are ____________________.
Same-side interior angles are _______________________.
Alternate interior angles are ____________________.
Alternate exterior angles are ____________________.
4. Drag point D to the right and left. Are these relationships are still true when the angles change?

__binder paper__which will be stamped when you complete the investigation. 1. Check each box and observe where each pair of angles is located. Describe the following: Corresponding angles - Same-side interior angles - Alternate interior angles - Alternate exterior angles - 2. Use the angle tool to measure each pair of angles listed below and record their measures:__Corresponding__: m__Same-side interior__: m__Alternate interior__: m__Alternate exterior__: m
