Question

1) After striking a pair of arcs from each endpoint of a line segment, what is the next step in constructing the segment's perpendicular bisector?

Answer 1

After striking a pair of arcs from each endpoint of a line segment, just join the intersection point of the 1st pair (above the segment) with the intersection point
of the 2nd pair (under the segment)
And this is how you construct the segment's perpendicular bisector

Answer 2

C) Use a straight edge to draw a vertical line between the points where each pair of arcs intersect.
