In two dimensions: They are parallel if their gradients are the same. They are perpendicular if the product of their gradients is -1. Otherwise they are neither. The nature of the question suggests that you have not yet studied lines in 3 or more dimensions.

Parallel

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, oblique lines are neither parallel nor perpendicular

Parallel

Diagonal

That depends on the specific situation. You may want to measure angles (perpendicular lines are at a right angle, i.e., 90Â°). If you have equations for line, write them in the slope-intercept form. Parallel lines have the same slope. If lines are perpendicular, the product of their slopes is -1.

Lines that are neither parallel nor perpendicular.

= 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.

neither

Lines that are neither parallel nor perpendicular.

If the slope of the equations are the same then they are parallel If the slope of the equations are minus reciprocal then they are perpendicular If the slope of the equations are different then they are neither

Neither: because one line, by itself, can be neither parallel or perpendicular. These characteristics are relevant only in the context of another line (or lines). The given line is parallel to some lines and perpendicular to others.
