100
Any line that intersects two or more coplanar lines.
What is a transversal
100
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.
What are Same Side Interior Angles (Consecutive Interior)
100
Two angles are congruent. 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 are linear pairs, what is their relationship
What is supplementary
100
If a transversal cuts two parallel lines, how many angle measures do you need to know to figure out all 8 angle measures in the figure.
What is 1.
200
Two angles whose measures add up to 180 degrees
What are supplementary angles
200
Two angles whose measures add up to 90o
What are Complementary Angles.
200
What is the relationship between angles 4 and 5?
What are Alternate Interior Angles.
200
One way to prove that lines are parallel lines is through understanding that corresponding angles are
What is congruent
200
If a transversal cuts two non-parallel lines, at least how many angles do you need to know to figure out all 8 angles in the figure?
What is 2.
300
When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.
What are Corresponding Angles.
300
A pair of adjacent angles formed by intersecting lines.
What are Linear Pair Angles.
300
If the measure of angle 8 is 112, what is the measure of angle 6?
What is 68.
300
To prove that lines are parallel one must understand that same side interior angles are
What is supplementary
300
If the measure of <1 is 4x-6 and the measure of <8 is 122, what is the value of x?
What is 4x-6=122 +6 +6 4x=128 x=32
400
Congruent angles formed by two intersecting lines
What are Vertical Angles.
400
If two parallel lines are intersected by a transversal these angles are located on the outside of the two parallel lines and on the same side of the transversal.
What are Same Side Exterior Angles.
400

What is the relationship between angles 1 and 4?

What are Vertical Angles.

400

If the measure of angle 2 is 30, what is the measure of angle 7?

What is 30.

400
If the measure of <3 is 150 and the measure of <6 is 3x, what is the value of x and what is the measure of <7?
What is <7=150; and 3x=150 x=50
500
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.
What are Alternate Interior Angles.
500
Coplanar lines that do not intersect.
What are parallel lines.
500

If the measure of angle 1 is 37, what is the measure of angle 8? What is the angle relationship

What is 37, Alternate Exterior

500
Given that l || m, m<1=98°, then the measures of <3 and <8 are:
What is 82 and 98 respectively
500

If the measure of <4 is 8x+35 and the measure of <6 is 2x+5, then find the value of x and find the measure of <8?

What is 8x+35+2x+5=180 10x+40=180 10x=140 x=14 Now plug into <4 because it is congruent (corresponding) to <8. 8(14)+35=112 so <8=147.
