| 
								Ruler Postulate									 | 
								Points on a line can be  matched   w/  real #,  distance btween pts A & B is abs. value of diff btween coordinates of A & B									 | 
| 
								Segment Addition Postulate									 | 
								Allows you to add two two smaller segements to get a bigger one									 | 
| 
								Angle Addition Postulate									 | 
								 Allows you  to add to smaller angles 2 get a bigger  one									 | 
| 
								LInear Pair Postulate									 | 
								 If two angles form a linear pair, then they are supplementary									 | 
| 
								Parallel Postulate									 | 
								If there's a line & a point no on the line, then there's exactly one line parallel toda given line through that point									 | 
| 
								Perpendicular Postulate									 | 
								Its just like Parallel Postulate only thing is that all parallels change to perpendicular									 | 
| 
								Corresponding Angle Postulate									 | 
								If 2 parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent									 | 
| 
								Corresponding Angles Converse									 | 
								If 2 lines are cut by a tranversal so that corresponding angles are congruent, then the lines are parallel									 | 
| 
								Right Angle Congruence Thrm									 | 
								All right angles are congruent									 | 
| 
								Congruent Supplements Thrm									 | 
								If 2 angles are supplementary to same angle (or to congruent angles) then the  2 angles are congruent									 | 
| 
								Congruent Complements Thrm									 | 
								If 2 angles are complementary to the same angle (or to congruent angles) then the 2 angles are congruent									 | 
| 
								Vertical Angles Thrm									 | 
								Vertical angles are congruent									 | 
| 
								Alternate Interior Angles Thrm									 | 
								If 2 parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent									 | 
| 
								Consecutive Interior Angles Thrm									 | 
								If 2 parallel llines are cut by a transversal, then the paris of consecutive interior angles are supplementary									 | 
| 
								Alternate Exterior Angles Thrm									 | 
								If 2 parallel lines are cut by a transversal, then the pairs  of alternate exterior angles are congruent									 |
