A student wrote the steps down for constructing a line perpendicular to a given line through point K, a point on the given line.
1. With the point of the compass on K, conštruct arcs with the same radius on the
line, one to the right of K and the other to the left. Label these points J and L.
2. Place the point of the compass on point ), open the width of the compass past
point K, and mark an arc above the line.
3. Adjust the compass width, center it at point L, and mark an arc above the line.
4. Draw a line through K and the intersection of the arcs above the line.

In which step did the student make an error?

a. step 1
b. step 2
c. step 3
d. step 4

Please provide an explanation if you can! Thanks!!
