10
When two lines have the same slope and go on forever without touching.
Parallel Lines
10
Are angle 1 and angle 8 congruent? Why/Why not?
Yes. They are opposite exterior angles.
10
What is the measure of angle 5?
115o
20
The line that cuts through two parallel lines.
Transversal
20
Are angle 3 and angle 6 congruent? Why/Why not?
Yes. They are opposite interior angles.
20
What is the measure of angle 4?
30o
30
What kind of angles are these?
Alternate Interior Angles
30
Are angle 3 and angle 5 congruent? Why or why not?
No. They are same-side interior angles which means they add to be 180 degrees.
30
What is the measure of angle 8?
70o
40
What kind of angles are these?
Alternate Exterior Angles
40
Are angle 1 and angle 6 congruent? Why or why not?
No.
Example answer: angle 1 and angle 5 are corresponding angles, and angle 5 and angle 6 make a straight line, so angle 1 and angle 6 are not congruent.

50
What kind of angles are these?
Corresponding Angles
50
Are angle 2 and angle 8 congruent? Why or why not?
No. Example answer: angle 2 and angle 6 are corresponding angles and angle 6 and angle 8 make 180 degrees so angle 2 and 8 are not congruent.
