Steps of construction:- 

(i) Draw a line segment AB having a length of 4 cm.

(ii) Now, construct a right angle at point A and make a line of 3 cm.

(iii) Name this point C. Thus \Delta ABC is the required triangle.

(iv) Draw a line AX which makes an acute angle with AB and is opposite of vertex C.

(v) Cut four equal parts of line AX namely  AA1, AA2, AA3, AA4, AA5.

(vi) Now join A3 to B. Draw a line A5B' parallel to A3B.

(vii) And then draw a line B'C' parallel to BC.

Hence \Delta AB'C' is the required triangle.
