Properties of parallel lines cut by a transversal Flashcards
(7 cards)
If two parallel lines are cut by a transversal then corresponding angles are congruent
Corresponding Angle postulate
If two parallel lines intersected by a transversal, then alternate interior angles are congruent
Alternate Interior Angles
If two lines are cut by a transversal and the alternate interior angles are congruent, then the lines being cut by the transversal are parallel
Converse Alternate Interior Angle Theorem
If two parallel lines are intersected by a transversal then
Same side interior angles are supplementary
Same Side interior of angles theorem
If two parallel lines are intersected by a transversal then the alternate exterior angles are congruent
Alternate Exterior angles
If two parallel lines are intersected by transversal, then same side exterior angles are supplementary
Same side exterior of angles theorem
If parallel line is perpendicular to one line that is parallel to another, then the line is perpendicular. To tge second parallel lines
Perpendicular transversal theorem
