perpendicular
Perpendiculars: perpendicular means right angle i.e. 90⁰. If you consider the normal houses, the angle between the walls and the ground is 90⁰. That means these are perpendicular planes. Perpendicular to a line means any line which makes an angle of 90⁰ with it. We can draw perpendicular line to a given line in different ways. They are as follows 1) Perpendicular from a given point: This is the construction of a perpendicular to a line a from a given point which is non collinear.
