*X*and

*Y*are two moving points in the polygon.

(a) On the diagram, draw

(i) the locus of the point

*X*such that

*XQ*=

*XR*.

(ii) the locus of the point

*Y*such that

*YQ*=

*QR*.

(b) Hence, mark with the symbol $$

*X*and the locus of

*Y*.

**Question 8:**

Diagram below shows a Cartesian plane.

Draw the locus of

*X*,

*Y*and

*Z*.

(a)

*X*is a point which moves such that its distance is constantly 4 units from the origin.

(b)

*Y*is a point which moves such that it is always equidistant from point

*K*and point

*L*.

(c)

*Z*is a point which moves such that it is always equidistant from lines

*KM*and

*y-*axis

*.*
