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