I have tried but still cannot get it. Simple geometry question.
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
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.....
