A point moves such that it is equidistant from two fixed points, H and K.

The locus of the moving point is

• an arc that joins points H and K.

• a perpendicular bisector of the straight line that joins points H and K.

• a circle that passes through points H and K.

• a line that is parallel to the line joining points H and K.
