Perpendicular lines are any two lines that intersect at a 90 degree angle.
They are what makes it a rectangle. The rectangle is a special kind of parallelogram. The perpendicular lines cause it to be called a rectangle.
Technically, equations are never perpendicular to one another. However, the equations of lines can result in their lines being perpendicular. Using y=mx+b, to have a perpendicular line, you have the negative reciprocal of m.
A rectangle has four 90º (right) angles. A right angle makes lines or line segments perpendicular to each other.
Perpendicular lines are ones that make right angles when they meet. For instance the letters T H E and L are all made of perpendicular line segments.
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.

perpendicular.... it makes a right angle
