Steps of Construction :

            1.         Draw a line AB = 4.8 cm

            2.         With A as center, mark an arc of 3.6 cm radius and with B as center, cut the arc with 3 cm radius at point C.

            3.         Draw the line AC and BC which are of length 3.6 cm and 3 cm respectively.

            4.         With A as center, draw an arc which cuts AB and AC at point F, E respectively.

            5.         With E and F as center, draw arcs which intersect at G.

            6.         Draw line AD which passes through G,

                        D is mid-point of BC.

                        A is the smallest angles because the angle in front of the smallest side is the smallest.

                    \angle CAB =38^{\circ}, \angle ABC = 50^{\circ}, \angle ACB =92^{\circ}
