What is the fourth step in construction of perpendicular bisector of the line segment AB? Draw a line segment using the ruler. Label it AB. Draw a line from X to Y. The line XY is the perpendicular bisector of the line segment AB. Without changing the compass setting, place the pointed end of the compass on B. Draw arcs above and below the line segment to cut the first two arcs. Mark the points where these arcs meet. Call them X and Y. Place the pointed end of the compass on A and draw arcs above and below the line segment.
