**To construct:** Δ ABC where m∠ A = 60**°** , m∠B = 30**°** and AB = 5.8 cm.

**Steps of construction:**

(a) Draw a line segment AB = 5.8 cm.

(b) At point A, draw an angle ∠ YAB = 60**°** with the help of compass.

(c) At point B, draw ∠ XBA = 30**°** with the help of compass.

(d) AY and BX intersect at the point C.

It is the required triangle ABC.
