Question

Conustruct a triangle abc,bc=4.7angleb= 45°,ab-ac=2cm

Answer 1

1) draw the base BC and at point b Make an angle,given of 45°

2) cut a line segment BD equal to AB -AC of 2 cm

3) then join DC

4) then draw perpendicular bisector PQ of DC

5) it intersect BD at A. Join AC.

Here ∆ABC is your required triangle
