Question

Construct triangle $ABC$ in which $BC=6cm,AB-AC=3.1cm$ and $\angle B={30}^{\circ }$

Answer 1

1. Draw a line $BC=6cm$

2. Construct ${30}^o$ at $B$. Extend $BP$.

3. Take $3.1cm$ on compass, cut an arc on $BP$. Join $CX$.

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