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

9

## Alternate Exterior Angles Theorem

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