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 opposite. The measure of the first angles is 42 degrees, what is the measure of the second angle
What is 42
100
If a pair of adjacent angles formed by intersecting line add to 180, what is their relationship?
What is supplementary
100
If a transversal cuts two parallel lines, how many angles are formed?
What are 8
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 ? 
What are Alternate Interior Angles (Z or N).
200
If the measure of angle 4 is 100 degrees, what is the measure of angle 5, and why?
What is 100 degrees because they are alternate interior angles.
200
What is the measure of angle a, and why?
What is 50 degrees because they're complimentary.
300
These angles are equal and form an F pattern.
What are Corresponding Angles.
300
Supplementary angles
A pair of adjacent angles formed by intersecting lines. These angles are also supplementary.
300
If the measure of angle 4 is 112, what is the measure of angle 6?
What is 68. (co-interior angles)
300
If the measure of angle 6 is 72 degrees, what is the measure of angle 4, and why?
What is 108 degrees since they are co-interior.
300
What is the measure of angle c, and why?
What is 60 degrees because they're supplementary.
400
What are opposite angles?
Equal 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?
What are opposite Angles.
400
If the measure of angle 2 is 30 degrees , what is the measure of angle 6, and why?
What is 30, because they are corresponding.
400
What is the measure of angle g, and why?
What is 50 degrees because they're opposite.
500
What are Alternate Interior Angles?
Two angles that are equal that form a N or Z pattern.
500
Co-interior 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?
What is 37 and Alternate Exterior.
500
If the measure angle 5 is 98 degrees, what is the measure of angles 3 AND 4, and why?
What is angle 3 =82 degrees because they are co-interior and angle 4= 98 degrees because they are alternate interior.
500
What is the measure of angle i, and why?
What is 48 degrees because they're complementary.
