perpendicular.

PERPENDICULAR

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.

As far as we know, two lines can be perpendicular, or they can be parallel, but they can't be both.

PARALLEL AND PERPENDICULAR LINESParallel lines can run side by side on forever but perpendicular lines make a 90 degree angle.

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.

A rhombus has parallel lines but no perpendicular lines.

Right triangles have a set of perpendicular lines and no parallel lines.

No, perpendicular lines intersect eachother at 90 degree angles. Parallel lines never intersect. So perpendicular lines will never be parallel.

PERPENDICULAR

perpendicular.

Perpendicular: No Parallel: Yes, two pairs.

Construction, engineering, drawing, and architecture all use parallel and perpendicular lines. Other than that, it is an important topic because you are learning how to apply the language and tools of mathematics to an intuitive system. These topics have proven important in the history of human kind and also many before you have shown that by learning about parallel and perpendicular lines, one learns how to use math and logic. It is doubtful that you can make a living off of parallel and perpendicular lines, but if you can't understand parallel and perpendicular lines, then I worry about your future.

A trapezoid has 2 parallel lines. It may or may not have perpendicular lines.

Parallel. Latitude and longitude are perpendicular.

Parallel lines are never perpendicular. Perpendicular lines are co-planar and cross at right angles.
