Draw \[\Delta \]PQR with PQ = 4 cm, QR = 3.5 cm and PR = 4 cm. What type of triangle is this?

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.
