Loci for 2 fixed points

For 2 fixed points, the Loci is the perpendicular bisector. For example, if the question was 'Draw the Locus that remains equidistant (equal distant) from points A and B' To do this, you would:

• Join both points with a straight line
• Place compass at point A, set over halfway and draw 2 arcs
• Do the same with point B
• Make perpendicular line from the 2 intersections
