Question

In ∆ABC, points P and Q are on CA and CB, respectively such that CA = 16 cm, CP = 10 cm, CB = 30 cm and CQ = 25 cm. Is PQ || AB?

Sum

Solution

Given: `AC=16cm,CP=10cm,CB=30cm` and `CQ=25cm`, we get

We will check whether  `(CP)/(AC)=(CQ)/(BC)` or not to conclude whether `PQ||AB`.

`(CP)/(AC)=(10cm)/(16cm)=5/8`

`(CQ)/(CB)=(25cm)/(30cm)=5/6`

`∴ (CP)/(AC)≠ (CQ)/(CB)`

Hence, PQ is not parallel to AB.
