3.5 Flashcards
Corresponding angles
Two angles that occupy corresponding positions
Alternate interior angles
Two angles that lie between L and m on opposite sides of t
Alternate exterior angles
Two angles that lie outside of L and m on opposite sides of t
Consecutive interior angles
Two angles that lie between L and m on the same side of t
Corresponding angles postulate
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent
Alternate interior angles theorem
If two parallel lines are cut by a transversal, then the Pairs of alternate interior angles are congruent.
Consecutive interior angles thm
If two parallel lines are cut by a transversal, then the pairs of consecutive interiors angles are supplementary
Alternate exterior angles
Thm
If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.
Perpendicular transversal theorem
If a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the second
Transversal
A line that intersects two or more Coplanar lines at different points
