P

is a point

(a, b, c)

. Let

A, B, C

be the images of

P

yz, zx

and

xy

planes respectively, then equation of the plane passing through the points

A, B \text{ and } C \text{ is } \frac{x}{a} + \frac{y}{b} + \frac{z}{c} = 1

Statement II The image of a point

P

in a plane is the foot of the perpendicular drawn from

P
