| Properties of segment congruence theorem |
|
Definition
| segment congruence is reflexive, symmetric, and transitive |
|
|
Term
|
Definition
| if M is the midpoint of AB, then AM=1/2 of AB & MB=1/2 of AB. (a midpoint splits the segment into two equal parts) |

Term
| right angle congruence theorem |
|
Definition
| all right angles are congruent |
|
|
Term
| congruent supplements theorem |
|
Definition
| if 2 angles are supplementary to the same angle (or to congruent angles) then they are congruent |
|
|
Term
| congruent complements theorem |
|
Definition
| if two angles are complementary to the same angle then they are congruent |
|
|
Term
|
Definition
| an angle bisector splits the angle is two equal parts/angles |

Term
| alt interior angle theorem |
|
Definition
| if two parallel lines are cut by transversal, then alternate interior angles are congruent |
|
|
Term
|
Definition
| if a transversal is perpendicular to one or two parallel lines, its also perpendicular to the other |
|
|
Term
|
Definition
| if two lines are cut by a transversel, and alternate interior angles are congruent, then lines are parallel |
|
|
Term
| same side interior angle converse |
|
Definition
| if 2 lines are cut by a transversel, and same side interior angles are supplementary, then lines are parallel |
|
|
Term
| alternate exterior angle converse |
|
Definition
| if two lines are cut by a transversal, and alternate exterior angles are congruent, then lines are parallel |
|
