Question
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 =
∴ Distance of A(2, -3, 4) from XY - plane =
(ii) Distance of P(a, b, c) from ZX-plane =
∴ Distance of B(4, -3, 1) from ZX-plance =
(iii) Distance of P(a, b, c) from YZ-plane =
∴ Distance of C (3, -2, -1) from YZ-plane =
