If a point P lies in yz-plane, then the coordinates of a point on yz-plane is of the form ________.

(0, y, z)

Explanation:

∵ P lies in yz plane and x – coordinate gives the perpendicular distance of a given point from yz plane.

∴ x coordinate of P is 0

But still point P has some perpendicular distances from xy and xz planes. So we define this point by (0, y, z) where y is the perpendicular distance from point P to xz plane and z is the ⊥ distance from point P to xy plane.
