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
