Which step in the construction of copying a line segment ensures that the new line segment has the same length as the original line segment

Answer:
There is no image here so I can't answer this question based on the picture but I can say that the one of the endpoints on the new line segment needs to be congruent to one of the endpoints to the original line segment drawn. The arcs that are swung also should use the endpoints of the line segments.
Answer:
The second step ensures that the new line segment has the same length as the original segment.
Step-by-step explanation:
The steps to copy a line segment:
1. Move the compass center to point P.
2. Adjust the radius of the compass to the length of the original line segment (PQ).
3. Move the compass center to R.
4. Draw an arc that intersects the line to the right of R.
