Question

If A, B, C are the feet of perpendicular from a point P on the XY, YZ and plane respectively, then find the distance of A, B and C in each of the following, where the point P is.

(i) (-5, 3, 7) 

(ii) (4, -3, -5)

Answer 1

(i) (-5, 3, 7) Distance of A from XY plane is 7 units 

Distance of B from YZ plane is 5 units 

Distance of C from ZX plane is 3 units

 (ii) (4, -3, -5) Distance of A from XY from XY plane is 5 units 

Distance of B from YZ plane is 4 units 

Distance of C from ZX plane is 3 units
