In geometric terms, one line is said to be perpendicular to another when their angle of intersection is 90°
A perpendicular line is one which intersects another line at 90 degrees (or at right angles).
Perpendicular lines are, by definition, lines which are at right angles to another line. In other words in a capital letter T the vertical line is perpendicular to the horizontal one because they are at right angles (90 degees) to one another.
Yes, perpendicular lines intersect at right angles which have 90 degrees.
Technically, equations are never perpendicular to one another. However, the equations of lines can result in their lines being perpendicular. Using y=mx+b, to have a perpendicular line, you have the negative reciprocal of m.
