100
Any line that intersects two or more coplanar lines.
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.
Same Side Interior Angles
100
Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle

200
One way to prove that lines are parallel lines is through understanding that corresponding angles are
Congruent
200
If the measure of angle 8 is 112, what is the measure of angle 6? 
68 degrees
300
When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.
Corresponding Angles.
300
A pair of adjacent angles formed by intersecting lines.

300
If the measure of angle 8 is 112, what is the measure of angle 6?
68 degrees
300
To prove that lines are parallel one must understand that same side interior angles have what relationship?
Supplementary
300
If the measure of <1 is 4x-6 and the measure of <2 is 122, what is the value of x?
x = 16
400
Congruent angles formed by two intersecting lines
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.
Same Side Exterior Angles
400
What is the realtionship between angles 1 and 4?
What are Vertical Angles.
400
If the measure of angle 2 is 30 degrees , what is the measure of angle 7?
30 degrees
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?
<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.
Alternate Interior Angles.
500
Lines that do not intersect nor meet.
Parallel lines
500
If the measure of angle 1 is 37 degrees, what is the measure of angle 8? What is the angle relationship?
37 degrees, Alternate Exterior
500
Given that l || m, m<1=98°, then the measures of <3 and <8 are:
82 degrees and 98 degrees 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?
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=112.
