Perpendicular is when two lines cross... Parallel is when two lines never meet.... _____________ _____________ = PARALLEL LINES If they cross they are perpendicular, if they don't, they are parallel.

Yes, parallel means that two lines do not cross but lay side-by-side. Perpendicular is the opposite of parallel and means two lines intersecting.

Two lines are parallel if and only if they have the same slope. Two lines are perpendicular if the product of their slopes is -1. If neither of these conditions are met, the lines are nether parallel, or perpendicular.

Two lines that are not parallel are perpendicular. The symbol is +.

since one parallel lines is perpendicular to another line, the other parallel line is perpendicular to the line as well. so the two would not be parallel, only the original two.

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.

Railroad tracks or the number 11 are parallel lines. A cross or a small t are perpendicular lines. Also the two ll's in the middle of parallel are parallel lines.

Yes, parallel means that two lines do not cross but lay side-by-side. Perpendicular is the opposite of parallel and means two lines intersecting.

A perpendicular line is a line that creates two 90 degree angles at the line, segment, etc. that it intersects. Parallel lines are two lines that never intersect. Perpendicular lines cross at right angles (+) Parallel lines will never meet, no matter how far they are extended (=)

Perpendicular: No Parallel: Yes, two pairs.

No, you can't have two lines that are both parallel and perpendicular.

No, they can't. Perpendicular and parallel are antonyms.

Two lines are parallel if and only if they have the same slope. Two lines are perpendicular if the product of their slopes is -1. If neither of these conditions are met, the lines are nether parallel, or perpendicular.

Perpendicular if it is straight cross.

When two perpendicular lines cross, a right angle is formed.
