What is supplementary angles
100
states "If two angles form a linear pair, then the angles are supplementary."

100
a statement that can be proven.
What is theorem
100
two adjacent angles that have non common sides that form a line.
What is linear pair
200
two angles that have a sum of 90 degrees
What is complementary angles
200
states "If a=b and b=c, then a=c."
What is transitive property
200
states "If point B is on segment AC and between points A and C, then AB+BC=AC
What is segment addition postulate
200
states "Vertical angles are congruent."
What is vertical angle theorem
300
two nonadjacent angles that are formed by two intersecting lines.
What is vertical angles
300
states "If a is a real number, then a=a"
What is reflexive property
300
states "If two angles form a linear pair, then the angles are supplementary."
What is linear pair postulate
300
a statement that is accepted without proof.
What is postulate
400
angles that share a common side and a common vertex, and lie on opposite sides of their common side.
What is adjacent angles
400
states "If a=b, then a can be substituted for b."
What is substitution property
400
states "If point D lies in the interior of angle ABC, then m ABD + m DBC = m ABC"
What is angle addition postulate
400
states "If two angles are supplements of the same angle or of congruent angles, then the angles are congruent."
What is congruent supplement theorem
400
of equality states "If a, b, and c are real numbers and a=b, then a + c = b + c."
