Solution

The steps of construction are as follows.

1) Draw a line segment QR of length 3.5 cm.

2) Taking point Q as centre, draw an arc of 4 cm radius.

3) Taking point R as centre, draw an arc of 4 cm radius to intersect the previous arc at point P.

4) Join P to Q and R.

ΔPQR is the required triangle. As the two sides of this triangle are of the same length (PQ = PR), therefore, ΔPQR is an isosceles triangle
