Flashcards in 3.5 Properties of Parallel Lines Deck (10):
1

Transversal

A transversal is a line that intersects two or more coplanar lines at different points

2

Corresponding Angles

Two angles are cooresponding angles if they occupy cooresponding positions

3

Alternate Interior Angles

Two angles are alternate interior angles if they lie between two parallel lines on opposite sides of the transversal

4

Alternate Exterior Angles

Two angles are alternate exterior angles if they lie outside two parallel lines on opposite sides of the transversal

5

Consecutive Interior Angles

Two angles are consecutive interior angles if they lie between two parallel lines on the same side of the transversal

6

Corresponding Angles Postulate

If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent

7

Alternate Interior Angles Theorem

If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are congruent

8

Consecutive Interior Angles Theorem

If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are congruent

9

Alternate Exterior Angles Theorem

If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent

10

Perpendicular Transversal Theorem

If a transversal is perpindicular to one of two parallel lines, then it is perpendicular to the second
