 Linear Pair Postulate If two angles form a linear pair, then they are supplementary. i.e the sum of their measures is 180 degrees Transitive Property If a=b and b=c then a=c Congruent Supplements Theorem if two angles are supplementary to the same angle or to congruent angles then they are congruent Segment Addition Postulate If B is between A and C, then Ab+BC=AC If two lines are perpendicular... ...then they intersect to form 4 right angles Symmetric Property If a=b then b=a Alternate Interior Angles Theorem If two parallel lines are cut by a trasversal then the pairs of alternate interior angles are congruent Perpendicular Transversal Theorem If a transversal is perpendicular to one or two parallel lines, then it is perpendicular to the second Consecutive Interior Angles Converse If two lines are cut by a transversal so that consecutive interior angles are supplementary then the lines are parallel Alternate Exterior Angles Converse Theorem= If two lines are cut by a transversal so that alternate exterior angles are congruent then the lines are parallel Alternate Exterior Angles Theorem If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent. Congruent Complements Theorem If two angels are complementary to the same angle or to congruent angles, then they are congruent Corresponding Angles Converse If two lines are cut by a transversal so that corresponding angles are congruent then the lines are parallel Corresponding Angles Postulate If two parallel lines are cut by a transversal then the pairs of corresponding angles are congruent COnsecutive Interior Angles Theorem If two lines are cut by a transversal then the pairs of consecutive interior angles are supplementary Property of Perpendicular Lines If two coplanar lines are perpendicular to the same line then they are prallel to eachother. If two disinct lines intersect... ...then their interesection is exactly one point Reflexiver Property a=a Transitivity of Parallel Lines If two lines are parallel to the same line then they are parallel to eachother
