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

the next step is to construct side ps of the figure so that side ps is parallel and congruent to side qr. the chart below shows the steps each of the four students took to draw side ps:

student 1 fix the compass at m and adjust its width to point l. without changing the width of the compass, move the compass to n and draw a small arc on the big arc. label the point of intersection of the two arcs as t. draw a line segment from p that passes through t. adjust the width of the compass to qr and draw an arc from point p to intersect line pt at s.
student 2 fix the compass at m and draw an arc that intersects side qp at point t. without changing the width of the compass, move the compass to r and draw an arc. adjust the width of the compass to qr and draw an arc from point p. draw a line segment from r that passes through t and intersects the second arc at s.
student 3 fix the compass at l and adjust its width to point m. without changing the width of the compass, move the compass to r and draw an arc which intersects qr at point t. draw a line segment from r that passes through t and intersects the arc at s.
student 4 fix the compass at l and adjust its width to point p. without changing the width of the compass, move the compass to r and draw an arc which intersects qr at point t. draw a line segment from r that passes through t and intersects the arc at s.
