Question

Which is the best definition of perpendicular lines?

a) Perpendicular lines have opposite slopes.
b) Perpendicular lines never touch or cross.
c) Perpendicular lines meet at a 90 degree angle.
d) Perpendicular lines have the same slope.

Answer 1

Perpendicular lines meet at a 90 degree angle.

Step-by-step explanation:

The best definition of perpendicular lines is that they meet at a 90 degree angle (c). Perpendicular lines are lines that intersect each other at a right angle, forming a 90-degree angle. This is illustrated by the fact that the lines in option c form a 270° angle when combined.
