In geometry, a branch of mathematics, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°). Always . lines a and b cannot be parallel. Two intersecting lines (perpendicular or not) will define a plane and are therefore coplanar. This completes the plane, because now parallel lines intersect at a point which lies on the line at infinity. Think of two sticks that you are holding perpendicular to each other. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron. They can intersect at any angle, but when the lines intersect at exactly 90° they are perpendicular lines. and stop touching the pencils, move them away from each other a bit in all three directions.

Parallel lines are two lines in the same plane that never intersect. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle. Looking at a 2-dimension, graph, they lie on the same plane. If two coplanar lines are perpendicular to the same line, then the two lines are parallel to each other, so the lines must be parallel to each other. Parallel lines must be coplanar.
