​

Answer 1

Answer:

a) Draw a line segment QR = 5 cm.

(b) Taking Q as centre and radius 4.5cm, draw an arc.

(c) Similarly, taking R as centre and radius 4.5 cm,

draw another arc which intersects first arc at P.

(d) Join PQ and PR.

It is the required isosceles Δ PQR

Answer 2

Answer:

Construction:

(i) Draw a line segment QR = 5 cm.

(ii) Taking R as center and radius 4.5cm, draw arc.

(iii) Similarly, taking Q as center and radius 4.5 cm draw another arc which intersects the first arc at point P

(iv) Join PR and PR

It is the required Δ PQR..
