Solution

Steps of construction:
1. Draw a line PQ = 5 cm.
2. With P as centre and 3.5 cm as radius, draw an arc above the line PQ.
3. With Q as centre and 3.5 cm as radius, draw an arc cutting the previous drawn arc. Name the point of intersection as point R.
Join RP and RQ. $△$ RPQ is the required isosceles triangle.
