Q. 20

A plane meets the

Answer :

As A, B and C are on the coordinate axes, coordinates of A, B and C will be


A = (a, 0, 0)


B = (0, b, 0)


C = (0, 0, c)


Also, centroid of a triangle joining (x1, y1, z1), (x2, y2, z2) and (x3, y3, z3) is




a = 3α, b = 3β, c = 3γ


Also, equation of a plane with intercept is



Where, a, b and c are x-intercept, y-intercept and z-intercept only


Therefore, Equation of given Plane
