Answer:
D.
Step-by-step explanation:
Step 1
Mark a point (A) hat will be one endpoint of the new line segment.
Step 2
Set the compasses' point on the point (B) of the line segment to be copied.
Step 3
Adjust the compasses' width to the point (C). The compasses' width is now equal to the length of the line segment(BC).
Step 4
Without changing the compasses' width, place the compasses' point on the the point (A) on the line you drew in step 1.
Step 5
Without changing the compasses' width, Draw an arc roughly where the other endpoint will be.
Step 6
Pick a point (D) on the arc that will be the other endpoint of the new line segment.
Step 7
Draw a line from (A) to (D)
Step 8
Done. The line segment (AD)
is equal in length (congruent to) the line segment (BC).
