Two coplanar lines that do not intersect.
What are parallel lines.
100
When two lines intersect, they form 2 equal _________ angles.
What is opposite angles.

The midpoint of the line segment formed between (11, 8) and (-10, 2)
What is the point (1/2, 5)
100
This is a closed figure made up of line segments, in which each line segment only intersects two others.
What is a polygon.
200
In Euclidean geometry, there can only be one of these in any given triangle; in spherical geometry, there can be at least 3.
What is a right angle.
200
Two lines that are not in the same plane and do not intersect.
What are skew lines.
200
If three angles all share the same vertex point, what is the sum of their values? (The total number of degrees)
What is 360 degrees.
200
The type of slope created between the points (22, 13) and (-4, -1). (Hint; is the slope increasing or decreasing?)
What is 13/7, an increasing or positive slope.
200
This is a polygon that is equangular and equilateral.
What is a regular polygon.
300
The three most important undefined terms in geometry (the basis of all geometry)
What is a point, a line, and a plane.
300
A line that intersects with another line at a perfect 90 degree angle AND cuts the second line perfectly in half at its midpoint, forming two equal line segments.
What is a perpendicular bisector.
300
The two angles formed by the hands of a clock at 9:10 and 2:15 are _________to one another
What is supplementary, what is a linear pair.
300
Point F is the midpoint of line EG. If EF = 5x and EG = 120, what is the value of x?
What is x = 12

What are congruent figures.
400
Jeneatte walked around a perfectly circular track 1 time. She started to take a second lap, but only went 1/3 of the way around before leaving the track. How many degrees did Jeneatte walk in total?
What is 480 dgrees, or one full revolution (360) plus 1/3 of a revolution (120).
