What are parallel lines?
300
This type of triangle has 2 equal sides and base angles.
What is an isosceles triangle?
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..(Describe their relationship)
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. They are located across from each other.
What are Vertical Angles.
400
This word is used to describe the steepness of a line. (rise/run)
What is slope?
400
What is the relationship between angles 3 and 7?
What are corresponding angles?
400
If the measure of angle 2 is 30 degrees , what is the measure of angle 6? What is their relationship?

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
These types of lines intersect at a right angle. Their slopes are opposite reciprocals.
What are perpendicular lines?
500
If the measure of anlge 4 is 37o, what is the measure of angle 6? What is the angle relationship?
What is 143?, Same-side interior angles?
500
Given that l || m, m<1=98°, then the measures of <3 and <8 are:
What is angle 3 is 82 degrees? Angle 1 is 98 degrees?
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.
