| Question | Answer |
|---|---|
| segment addition postulate | if q is between p and r, then PQ + QR = PR |
| reflexive property | a=a |
| symmetric property | if a =b, then b=a |
| transitive property | if a=b, then b=c, then a = c |
| addition property | if a = b, then a + c = b + c |
| subtraction property | if a = b, then a - c = b - c |
| multiplication property | if a = b, then ac = bc |
| Division Property | if a = b and c is not equal to 0, then a/c = b/c |
| substitution Property | if a = b, then a may be replaced by b in any equation or expression. |
| Distributive Property | a(b + c) = ab + ac |
| vertical angles | two nonadjacent angles formed by 2 intersecting lines. vertical angles are congruent |
| linear pair | adjacent angles whose noncommon sides are opposite rays. sum = 180 degrees |
| complementary angles | two angles whose measures have a sum of 90 degrees |
| supplementary angles | two angles whose measures have a sum of 180 degrees |
| right angle | an angle whose measure is 90 degrees |
| acute angle | angles smaller than a right angle |
| obtuse angle | angles larger than a right angle |
| straight angle | has a measure of 180 degrees |
| collinear | points on the same line |
| coplanar | points on the same plane |
| bisector | intersects at its midpoint |
| midpoint | a point M is the midpoint of segment PQ if M is between p and Q and PM = MQ |
