Following are the steps of construction of a ∆ABC in which AB = 5 cm, ∠A = 30º and AC – BC = 2.5 cm. Arrange them and select the CORRECT option. (i) Draw ∠BAX = 30º (ii) Draw the perpendicular bisector of BD which cuts AX at C. (iii) Draw AB = 5 cm (iv) Join BD (v) Join BC to obtain the required triangle ABC (vi) From ray AX, cut off line segment AD = AC – BC = 2.5 cm A(i) → (iii) → (iv) → (v) → (vi) → (ii) B(iii) → (i) → (vi) → (iv) → (ii) → (v) C(iii) → (i) → (ii) → (v) → (iv) → (vi) D(iii) → (ii) → (iv) → (i) → (vi) → (v)
