perpendicular lines form a right angle at their intersection so draw the right angle symbol at the intersection

= 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.
Lines that intersect at 90 degrees are perpendicular lines
The only difference between perpendicular lines and intersecting lines is that perpendicular lines create a right angle at the point of intersection.
The definition of perpendicular lines also defines the angles -- perpendicular lines are two lines (or line segments) that meet at a 90 degree angle.
Intersecting lines may or may not be perpendicular. If the angle of intersection between two intersecting lines is 90 degrees, then the two lines are perpendicular. Otherwise, the lines are not perpendicular. For example: A | | | B ----|----- | | Here, the lines A and B are intersecting. The angle between A and B is 90 degrees. Therefore, line A and line B are perpendicular to each other.
