1
Q
Theorem
A
A statement that can be proved true by using established facts
2
Q
Adjacent Angles
A
Two angles that have the same vertex, share a common ray, and have no common interior points
3
Q
Complementary Angles
A
Two angles that sum up to 90°
4
Q
Complement Theorem
A
If the noncommon sides of two adjacent angles form a right angle, then the angles are complementary
5
Q
Supplementary Angles
A
Two angles that sum to 180°
6
Q
Linear Pair
A
Two adjacent angles whose non-common sides form opposite rays (form a straight angle)
7
Q
Supplement Theorem
A
If two angles form a linear pair, then they are supplementary
8
Q
Vertical Angles
A
Two nonadjacent angles formed by intersecting lines
