Parallel and Perpendicular Lines: An 8th Grade Challenge

2. A building is designed with a wall that is perpendicular to the ground. If the wall is 10 feet tall, what is the relationship between the wall and the ground?

• The wall is parallel to the ground.

• The wall is slanted at a 45-degree angle.

• The wall is perpendicular to the ground.

• The wall is horizontal to the ground.

3. Two streets in a city are parallel. If one street is 2 miles long and the other is 2.5 miles long, how can you identify that they are parallel?

• The streets are parallel if they are both 3 miles long.

• The streets are parallel if they are both located in the same neighborhood.

• The streets are parallel if they maintain a constant distance apart and have equal corresponding angles with a transversal.

• The streets are parallel if they intersect at a right angle.

4. A soccer field has goalposts that are perpendicular to the sidelines. If the distance between the goalposts is 8 feet, how does this relate to the sidelines?

• The distance between the goalposts (8 feet) is perpendicular to the sidelines.

• The distance between the goalposts is parallel to the sidelines.

• The distance between the goalposts is 8 feet along the sidelines.

• The goalposts are 8 feet apart from the center of the field.

5. A train track runs parallel to a highway. If the train track is 50 feet away from the highway, how can you determine that they are parallel?

• The train track is parallel to the highway because they intersect at one point.

• The train track and the highway are parallel if they are the same length.

• The train track and the highway are parallel if the distance between them remains constant.

• The train track and the highway are parallel if they are both straight lines.

6. A carpenter is building a frame for a door. If the top of the door frame is parallel to the floor, what can you say about the sides of the frame?

• The sides of the frame are horizontal and parallel to the floor.

• The sides of the frame are vertical and parallel to each other.

• The sides of the frame are slanted and meet at the top.

• The sides of the frame are curved and not parallel to each other.

7. A basketball court has lines that are perpendicular to the baseline. If the free-throw line is 15 feet from the baseline, how does this demonstrate perpendicularity?

• The free-throw line is parallel to the baseline.

• The free-throw line is perpendicular to the baseline because it forms a right angle with it.

• The free-throw line is 10 feet from the baseline.

• The free-throw line is at an angle to the baseline.
