Draw a segment.
Open your compass about 2/3 the length of the segment.
Place the needle of the compass on one endpoint.
Draw an arc (or two hash marks) from one side of the
segment to the other.
5. Move the needle of the compass to the other endpoint and
repeat the arc, keeping the compass the same size. You
should have two X’s on each side of the segment.
6. Connect the X’s by drawing a line. This line is a perpendicular
bisector of the segment.
