Solution

The rough sketch of the required ΔDEF is as follows.

The steps of construction are as follows.

1) Draw a line segment DE of length 5 cm.

2) At point D, draw a ray DX making an angle of 90° with DE.

3) Taking D as centre, draw an arc of 3 cm radius. It will intersect DX at point F.

4) Join F to E. ΔDEF is the required triangle.
