Mapping from 3-dimensional space (x,y,z) to 2-dimensional space (x',y') is given by the mapping functions: x'=x/z, y'=y/z. Map the square ABCD to the quadrilateral A'B'C'D', where the coordinates of the square are:
A(p,-p,p),
B(p,-p,2p),
C(2p,-p,2p)
and D(2p,-p,p).
What type of quadrilateral is generated by the mapping and what are the coordinates of the four vertices, A', B', C' and D'?
