Question

Construct triangle DEF such that EF =5cm ,m angle DFE=30,DF-DE=2cm

Answer 1

1. Draw EF = 5cm

2. Draw angle $\angle ={30}^{\circ }$

3. With F as centre and radius = DF = DE = 2cm, draw an arc.
Intersect it with the ray. Mark the points as A

4. Join AE

5. Draw a perpendicular bisector of AE

6. Extend the bisector to joint the ray which is ${30}^{\circ }$ from F. Mark the intersection point as D

7. Join DE.
We will get $\Delta$ DEF
