This postulate allows us to add or subtract the measures of segments.
What is the Segment Addition Postulate?
100
This word means to divide an angle or segment into 2 congruent angles or segments.
What is bisect?
100
These angles share a common vertex and are made up of 2 pairs of opposite rays.
What are vertical angles?
200
Two rays that have the same initial point that extend in opposite directions.
What are opposite rays?
200
These are points that lie on the same line.
What are collinear points?
200
The length of PQ, ST, and RP if Q is between P and S, R is between Q and S, S is between Q and T and PT=30, QS=16, and PQ=QR=RS.
What are PQ=8, ST=6, and RP=16?
200
These are the coordinates of the midpoint of a segment with endpoints (0,0) and (-8, 6).
What is (-4, 3)?
200
These angles do not have to be adjacent, but they always add to 90.
What are complementary angles?
300
In geometry, rules that are accepted without proof.
What are postulates?
300
These are points or lines that lie on the same plane.
What are coplanar?
300
This is the measure of angle DEF in #17.
What is 105?

What is (-5, 1/2)?
300
These angles do not have to be adjacent and always add to 180.
What are supplementary angles?
400
Two angles that share a common vertex and side, but no common interior points.
What are adjacent angles?
400
Draw five coplanar poits A, B, C, D, and E so that ray BA and ray BC are opposite rays and segment DE intersects line AC at B.

What is 100?
400
If two angles are supplementary and one of the angles measures 85, this is the measure of the other angle.
What is 95?
500
Two adjacent angles whose noncommon sides are opposite rays.
What is a linear pair?
500
Sketch two lines that are not coplanar and do not intersect.
What are skew lines?
500
This is the measure of angle HJL in #18.

500
This is the measure of angle SQP in #24.
What is 25?
