1. Warmup! Use the figure at right to: 1. Name the set of parallel lines.B C D E F G H I
Use the figure at right to:
1. Name the set of parallel lines.
2. Name a right angle.
3. Name a ray.
4. Name an acute angle.
5. Name two (2) obtuse angles.
6. Name three (3) lines.
7. Name the transversal. X

2. Vertical Angles
Vertical Angles are opposite angles that are made by the same lines. Vertical angles are congruent. 8
Name the pairs of
vertical angles: B A C F G D H

3. Corresponding Angles
Corresponding Angles have the same position on two different parallel lines cut by a transversal. Corresponding Angles are congruent. 8
Name the pairs of
corresponding angles: 8

4. Alternate Interior Angles
Are inside the parallel lines and on opposite sides of the transversal. Alternate Interior angles are congruent. 8
Name the pairs of
alternate interior angles: 8

5. Alternate Exterior Angles
Are on the outsides of the parallel lines in opposite places. Alternate Exterior Angles are congruent. 8
Name the pairs of
alternate exterior angles: 8

6. Use the list to name the angle relationship.
Alternate Interior Angles
Alternate Exterior Angles
Corresponding Angles
Vertical Angles 8
