Question

The figure below shows a partially completed set of steps to construct figure PQRS:

Two sides of a parallelogram PQRS are drawn. PQ that makes an acute angle with the horizontal side QR. QR extends to the left and an arc is drawn that cuts this extended line at L and the side QP at M. An arc of the same measure and the same orientation as arc LM is drawn from point R and intersects QR extended at N.

The next step is to construct side RS of the figure so that side RS is congruent to side PQ and angle PQR is congruent to angle SRN. The chart below shows the steps each of the four students
