Question

construct a triangle pqr in which PQ 5 cm qr 4.2 cm and median rs= 3.8 cm​

Answer 1

Answer:

Step-by-step explanation:

Construct a triangle PQR in which PQ= 5 cm,QR= 4.2 cm median RS =3.8cm.

PQ = 5 cm

QR = 4.2 cm

RS = 3.8 cm

as RS is median

=> PS = QS = PQ/2 = 5/2 = 2.5 cm

in ΔQRS

QS = 2.5 cm

QR = 4.2 cm

RS = 3.8 cm

All three sides are known

so we can construct triangle first draw any one line and then using compass next two arc can be cut to each other and by joining arc intersection point we will get triangle

now ΔQRS  is constructed

so we can just join PR

and now we will get ΔPQR
