Question

A and B are points on the sides PQ and PR respectively of a triangle PQR .If AP=2 cm, AQ=5cm, PB=4cm,BR=10cm,then AB/QR=

Answer 1

Answer:

From the dimensions given in the question,

Consider the △PQR

So, PQ/PA=12.5/5

=2.5/1

PR/PB=(PB+BR)/PB

=(4+6)/4

=10/4

=2.5

By comparing both the results,

2.5=2.5

Therefore, PQ/PA=PR/PB

So, AB is parallel to QR.
