Parallel And Perpendicular Lines Study Guide Page 2

Part I: Circle the word that best completes the sentence.

1. If two lines are parallel, then they (ALWAYS…..SOMETIMES…..NEVER) intersect.

2. If one line is skew to another, then they are (ALWAYS…..SOMETIMES…..NEVER) coplanar.

3. If two lines intersect, then they are (ALWAYS…..SOMETIMES…..NEVER) perpendicular.

4. If two lines are coplanar, then they are (ALWAYS…..SOMETIMES…..NEVER) parallel.

5. If two lines are cut by a transversal such that the alternate interior angles are

(CONGRUENT…..COMPLEMENTARY…..SUPPLEMENTARY), then the lines are parallel.

6. If two lines are cut by a transversal such that the consecutive interior angles are

(CONGRUENT…..COMPLEMENTARY…..SUPPLEMENTARY), then the lines are parallel.

7. If two lines are cut by a transversal such that the corresponding angles are

(CONGRUENT…..COMPLEMENTARY…..SUPPLEMENTARY), then the lines are parallel.

Part II: Think of each segment in the diagram as part of a line. Complete the

statement with PARALLEL, SKEW, or PERPENDICULAR.
