Angle Congruence and Reasoning with Deductive Reasoning Flashcards
Same Side Interior Angle Postulate
If there two parallel lines are cut by a transversal, then the same side interior angles are supplementary
Corresponding Angles Theorem
If there two parallel lines are cut by a transversal, then the corresponding angles are congruent
Alternate Exterior Angle Theorem
If two parallel lines are cut by a transversal, then the alternate exterior angles are congruent
Same Side Exterior Angle Theorem
If there two parallel lines are cut by a transversal, then the same side exterior angles are supplementary
Alternate Interior Angle Theorem
If there two parallel lines are cut by a transversal, then the alternate exterior angles are congruent
Congruent Supplements Theorem
If two angles are supplementary to the same angle, then they are congruent
Congruent Complements Theorem
If two angles are complementary to the same angle, then they are congruent
Same Side Interior Angle Postulate Converse
If two lines and a transversal form same side interior angles that are supplementary, then the two lines are parallel
Corresponding Angles Theorem Converse
If two lines and a transversal form corresponding angles that are congruent, then the two lines are parallel
Alternate Exterior Angle Theorem Converse
If two lines and a transversal form alternate exterior angles that are congruent, then the two lines are parallel
Same Side Exterior Angle Theorem Converse
If two lines and a transversal form alternate exterior angles that are supplementary, then the two lines are parallel
Alternate Interior Angle Theorem Converse
If two lines and a transversal form alternate interior angles that are congruent, then the two lines are parallel
Reflexive Property of Equality
A=A
Transitive Property of Equality
If a = b and b = c, a = c
Symmetric Property of Equality
if a = b then b = a
