Question
Construct $\triangle\text{ABC}$ in which $BC = 4\ cm$, $\angle\text{B}=50^\circ$ and $\angle\text{C}=70^\circ.$
✓
Answer
Steps of construction:
Step I: Draw a line segment $BC$ of length $4\ cm$.
Step II: Draw $\angle\text{CBX}$ such that $\angle\text{CBX}=50^\circ.$
Step III: Draw $\angle\text{BCY}$ with $Y$ on the same side of $BC$ as $X$ such that $\angle\text{BCY}=70^\circ.$
Step IV: Let $CY$ and $BX$ intersect at $A$.
Step V: $ABC$ is the required triangle.
