Question
Draw $\triangle\text{DEF}$ such that DE= DF= 4cm and EF = 6cm. Measure $\angle\text{E}$ and $\angle\text{F}.$
✓
Answer
Steps of construction:
Step I: Draw a line segment EF of length 6cm.
Step II: With E as centre, draw an arc of radius 4cm.
Step III: With F as centre, draw an arc of radius 4cm intersecting the previous arc at D.
Step IV: Join DE and DF to get the desired triangle DEF.
Step V: By measuring we get, $\angle\text{E}=\angle\text{F}=40^\circ.$
