To continue constructing a copy of ∠ABC, Soobin should use a compass to measure the distance between points A and C. This measurement corresponds to the angle's side (BC) and will help in replicating the angle at the new vertex (B1).
So the correct response is:
Using a compass, measure the distance between points A and C.
