The matrix that projects onto the *x-y* plane is\[\begin{bmatrix}1 & 0 & 0 \\0 & 1 & 0 \\0 & 0 & 0 \\\end{bmatrix}\]This matrix is a 3x3 transformation matrix used to project points from three-dimensional space onto the *x-y* plane. The third row consists of zeros, effectively removing the z-component of any point to achieve the projection onto the two-dimensional plane.

We have to find the matrix that project onto plane
