Question

Where do two perpendicular lines intersect?

Answer 1

Y-axis and X- axis are perpendicular to each other( only two axis) so these lines intercept in origin (o,o)

Answer 2

A line is said to be perpendicular to another line if the two lines intersectat a right angle. Explicitly, a first line isperpendicular to a second line if (1) the two lines meet; and (2) at the point of intersection the straight angle on one side of the first line is cut by the second line into two congruent angles.
