Two lines are perpendicular if they meet at a right angle.
Two lines which intersect to form right angles. (e.g.)
have slopes related by
lines that form right angles where they intersect.
Two lines, segments or rays that intersect to form right angles.
(n) Two or more lines that intersect once at a right angle (90 degrees), sometimes referred to as normal.
lines that lie on the same plane that intersect to form right angles (90 degrees). For example, lines and are perpendicular lines.
Lines with slopes that are negative reciprocals.
two lines that intersect at right angles.
Lines in the same plane that meet at 90 degrees. The slopes of perpendicular lines are negative reciprocals of one another. (m1)(m2)= -1
