Using ruler and a pair of compasses only, construct:
(a) (i) quadrilateral PQRS with |PQ| = 6 cm, |PS| = 8 cm, < PSR = 90(^o), |SR| = 12 cm and |QR| = 11 cm;
(ii) perpendicular from Q to cut (over{SR}) at K.
(b) Measure:
(i) IQRI;
(ii) < QRS.
Explanation
(a) The following solution was expected from the candidates
(b) (i) |QK| = 9.3cm
(ii) < QRS = 55(^o)
