The diagram shows the lines AB and BC. The point D is on the opposite side of AC to B. AD = 5 cm and CD = 6.5 cm. [Figure 20]

  1. (a)Construct quadrilateral ABCD.[1]
  2. (b)(i)On the diagram, construct the locus of points, inside the quadrilateral, that are equidistant from AB and BC,[1]
  3. (b)(ii)equidistant from B and C.[1]
  4. (c)The line PQ consists of the points, inside the quadrilateral, which are equidistant from AB and BC, and nearer to C than to B. Mark and label the line PQ on the diagram.[1]
