When two perpendicular lines cross, a right angle is formed.
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.
Perpendicular lines are any two lines that intersect at a 90 degree angle.
Non-perpendicular intersecting lines. There is no special name.
Perpendicular: No Parallel: Yes, two pairs.
When two perpendicular lines cross, a right angle is formed.
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.
