(a) Using only an unmarked ruler and a pair of compasses, construct a triangle ABC such that AB = 6\,cm, AC = 5\,cm and ∠A=50∘.
(b) Measure the length of BC correct to the nearest millimetre and write it on your diagram.
(c) Explain why no other non-congruent triangle can be drawn with the same three measurements.
