what are perppendicular lines?

Answer 1

Perpendicular lines are lines that intersect at a 90 degree angle.

Answer 2

In geometry, two lines are considered perpendicular (or orthogonal) if one falls on the other in such a way as to create congruent adjacent angles. The term may be used as a noun or adjective. Thus, referring to Figure 1, the line AB is the perpendicular to CD through the point B.

If a line is perpendicular to another as in Figure 1, all of the angles created by their intersection are called right angles (right angles measure ½π radians, or 90°). Conversely, any lines that meet to form right angles are perpendicular. The line AB does not have to end at B to be considered perpendicular

Answer 3

Perpendicular lines cross over at 90 degrees to the other (like a +), while parallel lines are those that run alongside eachother (like a =).
:D

Answer 4

two straight lines that cross each other at right angles. Think of a four way stop on the road. Those roads are perpendicular.

Answer 5

two lines that cross and at the point of intersection they form 90 degree angles.

Answer 6

One is horizontal, one is vertical
The first answer is parallel lines.

Answer 7

that other guy is wrong i am in algebra II just coming out of geometry and perpindicular means that they are intersecting

Answer 8

two lines running side by side that never intersect.
