Construct a triangle ABC in which BC = 8cm, `angleB=45^@` and AB - AC = 3.5 cm.

Explanation

Given that, in `DeltaABC`,
BC = 8 cm, `angleB = 45^(@)` and AB - AC = 3.5 cm
Steps of construction :
1. Draw the base BC = 8 cm
2. At the point B make an `angleXBC = 45^(@)`.
3. Cut the line segment BD equal to AB - AC = 3.5 cm from the ray BX.
4. Join DC.
5. Draw the perpendicular bisector, say PQ of DC.
Let it intersect BX at a point A.
7. Join AC.
