Question

0. 26.
In A PQR,PQ=7.8cm, QR=9.1 cm and PR=4.9cm. Find the
largest angle.​

Answer 1

Answer:

Steps of Construction:

 (i) Draw a line segment which is sufficiently long using ruler.

(ii) Locate points P and Q on it such that PQ=5.4cm.

(iii) At Q, construct a line segment QS, sufficiently large, such that ∠PQR=55˚ ; use protractor to measure 55˚

(iv) With Q as centre and radius 5.5cm, draw the line cutting QS at R; join PR.

Thus PQR is the required triangle.
