Question

Write the coordinates of the pt which is the reflection of the pt a b c in the xyplane

Answer 1

Toolbox:

The reflexion of the points in the xy palne. here the sign of the z coordinate changes.

The given point is (α,β,−γ)(α,β,−γ)

The reflexion of the points in the xy palne. where the sign of the z coordinate changes.

Hence the reflexion of the point (α,β,γ)(α,β,γ) in the xy plane is (α,β,−γ)(α,β,−γ)

The correct option is D
