-1
You have to know the slopes of both lines. -- Take the two slopes. -- The lines are perpendicular if (one slope) = -1/(the other slope), or the product of the slopes equals to -1.
Each of the four lines is perpendicular - to two of the other lines.
Perpendicular lines intersect at right angles to each other.
For any two perpendicular lines (save a vertical and a horizontal one), the product of their slopes is always -1. For two perpendicular lines with one having a slope of -2, the other will have a slope equal to -1 divided by -2, which equals 1/2.
It is impossible for parallel lines to be perpendicular. Perpendicular lines are intersecting lines, meaning that they cross each other. Parallel lines, on the other hand, are lines that never meet, no matter how far they are extended in either direction. So intersecting lines (which includes perpendicular lines) and parallel lines are exact opposites. Parallel lines will never meet or cross; they cannot be perpendicular.

Perpendicular lines can not be parallel to each other but they can be to other lines.
Each of the four lines is perpendicular - to two of the other lines.
perpendicular lines run at 90% angles to each other not Parallel
Lines that intersect each other at right angles are called perpendicular lines
Perpendicular lines intersect at right angles to each other.
For any two perpendicular lines (save a vertical and a horizontal one), the product of their slopes is always -1. For two perpendicular lines with one having a slope of -2, the other will have a slope equal to -1 divided by -2, which equals 1/2.

The lines that meet at right angles are perpendicular to each other.
Perpendicular lines intersect each other at 90 degrees
No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.
Perpendicular lines intersect to form right angles.
