Parallel+Perpendicular Lines

Aaron Nelson+Blake Tarver=<3

Parallel and Perpendicular lines are since are the measured slope of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope and lines with the same slope are parallel. Perpendicular lines are a bit more complicated
