Q. Which of the following is NOT an example of perpendicular lines?

Railroad tracks and railroad ties

Table legs and a tabletop

The dashed lines separating lanes

A four-way intersection

The rim and backboard of a basketball hoop

Q. How are perpendicular lines marked in figures?

Figures cannot denote perpendicular lines, so it must be explicitly stated

Matching tick marks are used to indicate perpendicular lines

A single box is placed in one of the angles created by the intersecting perpendicular lines

Four boxes are placed in the four angles created by the intersecting perpendicular lines

Any angles that look like right angles are assumed to be the result of perpendicular lines

Q. Which of the following is NOT true?

The intersection of perpendicular lines results in a right angle

The intersection of perpendicular lines results in four congruent angles

Perpendicular lines have negative reciprocal slopes
