Question

30. Trisha wants to create the perpendicular bisector of a line segments

AB. She places her compass of point A and opens it with the width more
than 1/2 the length of the line segment AB. She makes arcs above and
below the line segment. What could be Trisha's next step to create the
perpendicular bisector of line segment AB?
A
>connect the two arcs using a straightedge
B>connect each arc with point B using a straightedge
C>place the compass on the approximate midpoint and draw intercepting arcs
D>place the compass on point B and complete the same steps that she did for point A

Answer 1

The answer is D:

Place the compass on point B and complete the same steps that she did for point A

The process is that you draw arcs above and below the line from both ends, but it's crucial that the compass' radius is the same from both ends of the line. Then you draw the line that connects the two intersection points to form your perpendicular bisector.
