Question 8

1. Using ruler and a pair of compasses only, construct:
2. Parallelogram PQRS with RS as the base such that |PQ| = 7.8 cm,

|QR| = 5.6 cm and angle QRS = 120o;

• Rectangle ABRS, equal in area to parallelogram PQRS.
• Measure:
• |AP|;
• |AS|.

Observation

The Chief Examiner reported that this question was a very unpopular question as it was avoided by majority of the candidates. According to the report, majority of those who attempted it performed poorly.
Candidates were expected to draw a straight line and mark a point R on the line. Thereafter, they would locate point S by marking the point on the line which is 7.8 cm from R. At point R, they would construct angle 120o. They would then locate point Q such that |QR| = 5.6 cm. Candidates would then construct a line parallel to  such that it intersects  at S. They would then locate point P on this line such that |PS| = 5.6 cm and then draw the parallelogram. To construct a rectangle ABRS equal in area with Parallelogram PQRS, candidates were expected to construct perpendiculars from R and S respectively to intersect the line PQ produced at points A and B. ABRS would now be the required rectangle. The length AP was measured as 2.4 cm while |AS| was 4.9 cm.
