Question

what is the definition of perpendicular lines? perpendicular lines are two lines that share more than one common point. perpendicular lines are two lines that intersect to form four congruent right angles. perpendicular lines are two lines that cut each other in half. perpendicular lines are two lines that never intersect.

Explanation:

Perpendicular lines are defined by their intersection forming four equal right angles (90° each). The other options are incorrect: sharing more than one point describes coincident lines, cutting each other in half describes bisecting lines, and never intersecting describes parallel lines.

Answer:

Perpendicular lines are two lines that intersect to form four congruent right angles.
