Answer:
Given, three sides of ΔPQR are PQ = 4 cm, QR = 3.5 cm and PR = 4 cm. To construct a triangle with given sides, we use the following steps: Steps of construction: Step I: Firstly, we draw a rough sketch with given measures marked on it. Step II: Draw a line segment QR = 3.5 cm. Step III: With Q as centre and radius 4 cm, draw an arc. Step IV: Now, with R as centre and radius 4 cm, draw another arc to cut the previous arc at P. Step V: Join PQ and PR. Thus, ΔPQR is the required isosceles triangle.
