Question
Draw $\triangle\text{ABC}$ in which $\angle\text{A}=70^\circ,$ $AB = 4\ cm$ and $AC= 6\ cm$. Measure $BC$.
✓
Answer
Steps of construction:
Step I: Draw a line segment $AC$ of length $6\ cm$.
Step II: Draw $\angle\text{XAC}=70^\circ.$
Step III: Cut an arc on $AX$ at a distance of $4\ cm$ at $B$.
Step IV: Join $BC$ to get the desired triangle.
Step V: We see that $BC = 6\ cm$.
