What is the term used to describe lines or surfaces that are equidistant from each other and never meet?

• perpendicular

• intersecting

• parallel

Perpendicular Lines

• Lines that intersect to form acute angles; positive slopes

• Lines that never intersect; equal slopes

• Lines that intersect to form right angles; negative reciprocal slopes

• Lines that are parallel; have different slopes
