Question

Construct triangle $ABC$ in which $BC=5cm,AB-AC=2.8cm$ and $\angle B={40}^{\circ }$

Answer 1

1. Draw a line $BC=5cm$

2. Construct ${40}^o$ at $B$. Extend $BP$.

3. Take $2.8cm$ on a compass and cut an arc on $BP$. Join $CX$.

4. Take a perpendicular bisector of $CX$. It intersects with $BP$ at $A$.

5. Join $AC$
