Question
Draw $\triangle\text{ABC}$ in which $\angle\text{A}=120^\circ,$ $AB = AC = 3\ cm$. Measure $\angle\text{B}$ and $\angle\text{C}.$
✓
Answer
Steps of construction:
Step I: Draw a line segment $AC$ of length $3\ cm$.
Step II: Draw $\angle\text{XAC}=120^\circ.$
Step III: Cut an arc on $AX$ at a distance of $3\ cm$ at $B$.
Step IV: Join $BC$ to get the required triangle.
Step V: By measuring, we get $\angle\text{B}=\angle\text{C}=30^\circ.$
