I have tried but still cannot get it. Simple geometry question.(adsbygoogle = window.adsbygoogle || []).push({});

Tangents to the inscribed circle of triangle PQR are parallel to [QR], [RP] and [PQ]

respectively and they touch the circle at A, B and C.

Prove that [PA], [QB] and [RC] are concurrent

relevant formula:

Ceva's theorm (Any three concurrent lines drawn from the vertices of a triangle divide the sides (produced if necessary) so that the product of their respective ratios is unity/

Thank you in advance!

I have tried on geometry sketch pad. It did works.....
