How to construct Traingale with given data

first draw AB = 6cm and make a line AC at 60^o at point A.

now we have to find point C.

since it is given that median CD=5cm so we have to find a point on AC such that its distance from D (midpoint of AB )is 5cm. this can be easily done by using compass.that point will be point C.

now triangle with AB' can be drawn in the similar manner.
