The question, in short
Two mathematically similar triangles are shown: ABC with AB = 8 cm and BC = 6 cm, and PQR with PQ = 6 cm. Calculate the length QR.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 2 marks
- 1PQ matches AB, so scale factor = 6 ÷ 8 = 0.75
- 2QR matches BC: QR = 6 × 0.75
- 3QR = 4.5 cm
