A flat surface extending infinitely in all directions
What is a plane?
100
This is how you write the name of a segment.
What is you state the letters of both endpoints, and draw a line with no arrows above the letters.

Sketch 4 non-coplanar points.
sketch should show a plane, with three points on it and one off.
100
Two angles are supplementary. If one of them is 23 degrees, this is the measure of the other one.
What is 157 degrees?
100
Segment CD has a midpoint M. CM is 4x-2 and DM is 12x-42. Find the value of x.
What is 5?
200
You need exactly three points to define it.
What is a plane?
200
A segment is defined by points (-4, 7) and (1, -5). This is its length.
What is 13 units?
200
This word means "To have points in common with."
What is "to intersect?"

Elida says that Angle QRK and angle RKQ are the same exact angle. Is she right? Explain.
What is "No, the angles she names have a different vertex; the vertex must always be the middle point."
200
Angle CMD is bisected by ray MQ. The measure of CMQ is 3x, the measure of CMD is 8x-34. What is the measure of DMQ in degrees? (Draw picture, label, set up the equation)
What is 51?
300
The intersection of two planes
What is a line?
300
A segment is defined by points (-4, 7) and (1, -5). This is its midpoint.
What is (-3/2, 1)?
300
These angles are adjacent and supplementary.
What is a linear pair?
300
These are three ways to name an angle:
What is "using three letters," "by its vertex, if it's the only one with that vertex" and "using a number."
300
Two angles form a linear pair. One measures 6x-1 degrees, the other one measures 7x-1 degrees. Find the measures of both angles.
What is 83 degrees and 97 degrees?
400
These are points that are not on the same line.
What is non-collinear?
400
The midpoint of a segment is (-1, 5). One of the endpoints is at (3, -2). Where is the other endpoint?
What is (-5, 12)?
400
These angles are formed by intersecting lines, are across from each other and are congruent.
What are vertical angles?
400
Two angles are complementary. The measure of one angle is 10 less than three times the measure of the other. These are their measures.
What are 25 degrees and 65 degrees?
400
True/False? It is possible for two angles to be vertical and a linear pair at the same time. Explain. (no explanation, no credit)
What is False, because a linear pair must be adjacent, and vertical angles cannot be adjacent.
500
Define a ray.
What is a portion of a line with one endpoint that extends infinitely in one direction?
500
A line, segment or ray that divides a segment into two equal parts and forms 90 degree angles with it.
What is a perpendicular bisector?
500
These are angles whose measures add up to 90 degrees.
What is complementary?
500
Define Vertical Angles
What is Angles that share a vertex, are congruent, and whose sides form opposite rays?

If line n bisects CE at point D, the measure of CD is 3x+5 and the measure of DE is 8x - 15, then the measure of CE is....
