    Question 4.

    Proof. WE prove the following two things.

    (1) Verify that A->A', B->B', C->C' and D->D'
    In z plane, A<-> z=0, B<->z=1-i, C<->z=1, D<->z=1+i

    So, by mapping w(z)=z^2, we have
    w(A)=0^2=0, w(B)=(1-i)^2=-2i, w(C)=1^2=1 and w(D)=(1+i)^2=2i
    which correspond to A', B', C' and D' in the w-plane, respectively.

    We are done.

    (2) Triangle ABC is mapped to a parabola

    To prove this case, we want to show
    (a) the segment BD: x=1, y ...
