Answer:
It appears that the description for Student 3 provides the correct steps to construct side PS of rhombus PQRS. Therefore, **Student 3** used the correct steps for the construction.Student 3 used the correct steps to construct side PS of rhombus PQRS as follows:
1. Fixed the compass at L and adjusted its width to point M.
2. Without changing the width of the compass, moved the compass to R and drew an arc, intersecting QR at point T.
3. Drew a line segment from R that passed through T and intersected the arc at point S.
This process ensures that side PS is both parallel and congruent to side QR, meeting the criteria for constructing a rhombus. The correct use of the compass and sequential steps ensures the accuracy of the construction.
