100
What is a transversal
Any line that intersects two or more parallel lines.
100
Parallel lines
Straight lines that never intersect
100
Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle
42
100
When two angles share a side, what is the name of the angle relationship?
Adjacent angles
100
what kind of angles are < 1 and <4?
vertical
200
What are supplementary angles?
Two angles whose measures add up to 180 degrees
200
Complementary Angles
Two angles whose measures add up to 90
200
What is the relationship between angles 3 and 6 ? 
Alternate Interior Angles.
200
Are corresponding angles congruent or supplementary?
congruent
200
What kind of angles are <2 and <7?
alternate exterior
300
what are corresponding angles?
same position at the top and bottom
300
Corresponding Angles
A pair of angles formed by a transversal. They are on the same side of the transversal and in the same position. These angles are congruent.
300
If the measure of angle 4 is 112, what is the measure of angle 1?
112. (vertical angles)
300
Angles are either congruent or ______________ when working with parallel lines and transversals
supplementary
300
What kind of angles are <3 and <7?
Corresponding angles
400
What are vertical angles?
Congruent angles formed by two intersecting lines. These angles are located across from each other.
400
Alternate Exterior Angles
If two parallel lines are intersected by a transversal, these angles are located on the outside of the two parallel lines on opposite sides of the transversal.
400
What is the relationship between angles 5 and 8?
Vertical Angles.
400
If the measure of angle 2 is 30 degrees , what is the measure of angle 6?
30.
400
What kind of angles are <5 and <6
supplementary
500
What are Alternate Interior Angles?
When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal.
500
Consecutive Angles
If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.
500
If the measure of angle 2 is 37 degrees, what is the measure of angle 7? What is the angle relationship?
37 and Alternate Exterior.
500
Given that a || m, measure of angle 5=98°, then the measures of angles 6 and 4 are:
angle 6 =82 degrees and angle 4= 98 degrees
500
What kind of angles are <3 and <5?
Same side interior
