Observation

Candidates were expected to:

A.         COPY THE GIVEN VIEW

1. draw the base PQ;
2. draw PS at 105O to PQ;
3. locate point R and complete the quadrilateral PQRS.

B.         CONVERT TO TRIANGLE

1. produce PQ to a reasonable length;
2. join SQ and RT parallel to SQ;
3. complete triangle PTS.

C          CONVERT TO RECTANGLE

1. drop perpendicular from S to V and bisect SV;
2. draw rectangle PTMN.

D.            CONVERT TO SQUARE

1. draw TL = TM;
2. bisect  PL and draw semi-circle on PL;
3. produce TM to F and draw square TFGH.

E.         ENLARGE SQUARE

                        Alternative A

1. join FH;
2. draw perpendiculars from H and F;
3. complete the square FHJK.

OR
Alternative B

1. draw perpendicular for H and make HD = HT;
2. use T as centre and radius TD intercept PT produced at C;
3. complete the square TABC.

F.         (i)         use correct scale 1:1;
(ii)         measure and state the length = 58 ± 1;
(iii)        draw neatly.

The solution is shown below.
