200
One way to prove that lines are parallel lines is through understanding that corresponding angles are
What is congruent
200
What is the sum of the exterior angles of a octagon?
What is 360
300
When 2 parallel lines are intersected by a transversal, these angles occupy the SAME SIDE, one is in the INTERIOR and the other is EXTERIOR of the 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
What is the sum of the interior angles of a regular 25-gon?
4140 degrees
400
What is the relationship between angles 1 and 4?
What are Vertical Angles.
400

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 in the INTERIOR 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 37o, 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=112.
