Question

In the following figure, AB = 8.4 cm, PR = 5.0 cm and PQ = 4.8 cm; findthe lengths of BC, CA and QR.​

Answer 1

ANSWER:

Given, P, Q, and R are midpoints of AB, BC and CA respectively. 

Thus, by mid point theorem:

BC=2PR

BC=2(5)

BC=10 cm

Similarly,

 QR=21AB

QR=21(8.4)

QR=4.2 cm

and AC=2PQ

AC=2(4.8)

AC=9.6 cm
