Question

S
2. In A ABC, P and Q are points on sides AB
and AC respectively. For each of the following
cases, state whether PQ || BC or not :
(1) AP = 8 cm,
PB = 6 cm,
AQ=12cm
AC=21cm​

Answer 1

Answer:

In △ABC, PQ∥BC

So, by proportionality theorem

AP/PB=AQ/QC=PQ/BC

4/6=AQ/QC=3/BC

4/6=3/BC

Therefore, 4/6=3/BC
