Q. 335.0( 1 Vote )

The reflection of A. (α, β,0)

B. (0,0, γ)

C. (–α,–β, γ)

D. (α, β, –γ)

Answer :


The equation of XY plane is given by Z = 0


Given point (α,β,γ).


If we draw perpendicular from the point in the XY plane,


The coordinates of the point will be (α,β,0)


Let its reflection be (x,y,z)


So,



x = α



y = β



z = -γ


The reflection is:


(α , β ,-γ )
