Question

draw triangle PQR such that l(QR)=4cm, m angle PQR=80° l(PQ)=3cm. show orthocentre of the triangle​

Answer 1

To Construct : ∆PQR in which PQ = 4cm,

QR = 3.5cm and PR = 4cm

Steps of Construction :-

(a) Draw a line segment QR = 3.5cm

(b) Taking Q as centre draw an arc of

radius 4cm

(c) Similarly, taking R as centre and radius 4cm, draw an another arc which intersects first arc at P

(d) Join PQ and PR

Hence, it is an Isosceles Triangle
