Finding Angle Measurements Using Alternate Interior and Exterior Angles

This lesson teaches how to measure angles formed by parallel lines and a transversal using alternate interior and exterior angles. It reviews vertical, adjacent, and corresponding angles, clarifies the difference between interior and exterior angles, and demonstrates solving for angle values using equations. The lesson concludes with a summary of the key concepts covered.

Which of the following pairs are vertical angles?

• Angles 2 and 3

• Angles 3 and 5

• Angles 1 and 2

• Angles 1 and 4

What is the relationship between angles 3 and 7?

• They are alternate interior angles

• They are corresponding angles

• They are vertical angles

• They are adjacent angles

If angle 1 is congruent to angle 5, what type of angles are they?

• Alternate exterior angles

• Alternate interior angles

• Corresponding angles

• Vertical angles
