15. The Diagram in the answer space shows foursquares, PKJN, KQLJ, NJMS and JLRM.

W, X and Y are three moving points in the diagram.(a)W moves such that it is equidistant from the

straight lines PS and QR.

By using the letters in the diagram, state the locus

of W.

(b) On the diagram, draw(i) the locus of X such that XJ = JN,

(ii) the locus of Y such that its distance from point

Q and point S are the same.

(c)Hence, mark with the simbol all the intersections

of the locus of X and the locus of Y.
