Algebra Attack/Random Tidbits
100
Any line that intersects two or more lines.
Transversal Line
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.
Consecutive Interior
100
Two angles are congruent. The measure of the first angle is 42 degrees, what is the measure of the second angle
42
100
If a pair of adjacent angles formed by intersecting line are linear pairs, what is their relationship
Supplementary Angles

1
200
Two angles whose measures add up to 180 degrees
Supplementary Angles
200
Two angles whose measures add up to 90 degrees
Complementary Angles
200

200
One way to prove that lines are parallel lines is through understanding that corresponding angles are
Congruent
200
How many angles are produced when a transversal line intersects a pair of parallel lines?
8
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 angles that do not share a common vertex.
Non-adjacent angles
300
If the measure of angle 8 is 112, what is the measure of angle 6?
68
300
To prove that lines are parallel one must understand that same side interior angles are
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
Vertical Angles
400
If two parallel lines are intersected by a transversal these angles are located on the inside of the two parallel lines and on the same side of the transversal.
consecutive interior angles
400
What is the relationship between angles 1 and 4?
Vertical Angles
400
If the measure of angle 3 is 30 degrees , what is the measure of angle 5?
150 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?
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.
Alternate Interior Angles
500
Coplanar lines that do not intersect.
Parallel Lines
500
If the measure of angle 2 is 37 degrees, what is the measure of angle 7? What is the angle relationship?
37, Alternate Exterior
500
Given that l || m, m<1=98°, then the measures of <3 and <8 are:
Angle 3 is 82 and angle 8 is 98
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=112.
