Construct a △ABC in which BC = 3.4 cm, AB - AC = 1.5 cm and ∠B=45∘.
Steps of construction :
(i) Draw a line segment BC = 3.4 cm.
(ii) At B, draw a ray BX making an angle of 45∘ and cut off BE = 1.5 cm.
(iii) Join EC.
(iv) Draw the perpendicular bisector of CE which intersects BE produced at A.
(v) Join AC.
△ABC is the required triangle.
