Let A, B, C be the feet of perpendiculars from a point P on the x, y, z-axis respectively. Find the coordinates of A, B and C in each of the following where the point P is :
(i) A = (3, 4, 2) (ii) (–5, 3, 7) (iii) (4, – 3, – 5)
We already know that,
On x-axis, y,z= 0
On y-axis, x,z= 0
On z-axis, x,y = 0
Thus, from point P, the feet of perpendiculars will be-
