= 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.
That depends is it 3x + or - 9?

A rhombic octagon. An ordinary regular octagon does have perpendicular sides. They do not meet in the outline of the octagon because they are alternate, but they are still perpendicular. However, in the same way that a rhombus is a distorted square, a rhombic octagon can have 4 pairs of parallel sides but no perpendicular ones.
A parallelogram has 2 pairs of parallel lines and in the form of a rectangle it has 2 pairs of parallel lines and 4 perpendicular lines that meet at each of its corners at right angles.
