As far as we know, two lines can be perpendicular, or they can be parallel, but they can't be both.
draw two intersecting lines that are not perpendicular
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.

As far as we know, two lines can be perpendicular, or they can be parallel, but they can't be both.
Perpendicular is when two lines cross and form a right angle, which I hope you know what that is.
draw two intersecting lines that are not perpendicular
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.
Perpendicular lines are any two lines that intersect at a 90 degree angle.

Two lines are perpendicular or orthogonal if they meet at a 90 degree angle.For instance,|__|are two perpendicular lines.
Each of the four lines is perpendicular - to two of the other lines.
When two lines intersect at a right angle, they are "perpendicular"
When two perpendicular lines cross, a right angle is formed.
perpendicular crosses at a right angle, while intersecting lines don't
yes but they have to meet at a 90 degree angle to be perpendicular.
