Question 3

(a) The sketch in Fig. 3 shows points M and N, 50 apart. Point P moves such that
      its distance from M and N is always in the ratio of 2:1.


Fig. 3

      Plot the locus of point P for one revolution.

(b) The sketch in Fig. 4 shows two points, T and S, drawn above line XY.

       (i)  Construct a circle to touch line XY and pass through points T and S.
(ii) Measure and state the radius of the circle.

Observation

 

Candidates performed well in 3(b) but could not adequately give the required solution to 3(a)

The solution of the poorly attempted part of the question is as given below.
