Home » Aptitude » Plane Geometry » Question

The mid points of AB and AC of the ∆ ABC are P and Q respectively. If PQ = 6 cm., then the side BC is

1. 10 cm.
2. 12 cm.
3. 8 cm.
4. 14 cm.

Correct Option: B

As per the given in question , we draw a figure triangle ABC and P and Q are the mid points of AB and AC ,

The straight line joining the mid– points of the two sides of a triangle is parallel to the third side and half of it.
Here , PQ = 6 cm.
∴ BC = 2 × PQ = 2 × 6 = 12 cm.
