You want to find the midpoint of line segment JK by using a perpendicular bisector. Which of the steps below is NOT correct?

• Set the compass to less than halfway between J and K.

• Draw an arc centered on point J toward point K using the set radius.

• Draw a similar arc centered on point K toward point J.

• Connect the two intersecting points of the arcs to create a perpendicular bisector.
