VAT - Vertical Angles Theorem | All vertical angles are congruent |
LPP - Linear pair postulate | If two angles are a linear pair, then they are supplementary |
SAP - Segment addition postulate | if A, B, and C are collinear then AB + BC = AC (little + little = big) segment edition |
AAP - Angle addition postulate | If P is in the interior of angle RST, then the measure of angle RSP + measure of angle PST = measure of angle RST (little + little = big) angle edition |
