Answer 1

Answer:

steps to construction

1) draw a line segment AB = 8 cm

2) draw perpendicular bisector of line segment AB . meeting AB at M

3) taking M on centre draw an Arc of 4cm

4) join AC and BC .Then ∆ ABC so obtained in the required ∆ ABC

5) below AB, make an acute angle BAX

6) Along AX , mark 3 point A₁ ,A₂ and A₃ such that AA₁ = AA₂ = AA₃

7) join A₂B

8) From A₃ ,draw A₃B¹ parallel to A₂B .meeting AB produced at B¹

9) From B¹ draw B¹C¹ parallel to BC meeting AC produced at C¹ then AB¹C¹ in the required ∆
