3.5 Properties of Parallel Lines

Question 1

Transversal

Answer 1

Is a line that intersects two or more coplanar lines at different points

Question 2

Corresponding Angles

Answer 2

Two angles are corresponding angles if they occupy corresponding positions

Question 3

Alternate Interior Angles

Answer 3

Two angles are alternate interior angles if they lie between line l and line m, on opposite sides of the transversal

Question 4

Alternate Exterior Angles

Answer 4

Two angles are alternate exterior angles if they lie outside of line l and line m, on opposite sides of the transversal

Question 5

Consecutive Interior Angles

Answer 5

Two angles are consecutive interior angles if they lie between line l and line m, on the same side of the transversal

Question 6

Corresponding Angles Posulate

Answer 6

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

Question 7

Alternate Interior Angles Theorem

Answer 7

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

Question 8

Consecutive Interior Angles Theorem

Answer 8

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

Question 9

Alternate Exterior Angles Theorem

Answer 9

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

Question 10

Perpendicular Transversal Theorem

Answer 10

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