Find the perpendicular distance of:
(i) A (2, -3, 4) from XY-plane
(ii) B (4, -3, 1) from ZX-plane
(iii) C (3, -2, -1) from YZ-plane

Solution

(i) Distance of P(a, b, c) from XY-plane = open vertical bar straight c close vertical bar
∴ Distance of A(2, -3, 4) from XY - plane = open vertical bar 4 close vertical bar space equals space 4
(ii) Distance of P(a, b, c) from ZX-plane = open vertical bar straight b close vertical bar
∴  Distance of B(4, -3, 1) from ZX-plance = open vertical bar negative 3 close vertical bar space equals space 3
(iii) Distance of P(a, b, c) from YZ-plane = space open vertical bar straight a close vertical bar
∴ Distance of C (3, -2, -1) from YZ-plane = open vertical bar 3 close vertical bar equals 3
