An architect plans to draw a rectangular patio with segment LM representing one side of the rectangle. He wants to construct a line passing through Q and parallel to side LM. He uses a straightedge and compass to complete some steps of the construction as shown.

Is there a question in there somewhere?

To construct a line passing through point Q and parallel to segment LM, we can follow these steps:

1. Draw segment LM to represent one side of the rectangle.
2. Place the point of the compass on point Q and adjust its width to slightly longer than segment LM.
3. With the compass at this width, draw arcs on both sides of point Q, intersecting segment LM at two points, let's say A and B.
4. Without changing the width of the compass, place its point on point A and draw an arc above point Q.
5. Keeping the same width, place the compass point on point B and draw an arc intersecting the previous arc above point Q.
6. Finally, use a straightedge to draw a line connecting the intersection point of the two arcs above point Q and point Q. This line will be parallel to segment LM.

Note: The construction steps may vary slightly depending on the specific diagram provided.
