Given4ABC, let P,Q, andR be points on sides BC,AC, andAB, respectively, with RQ∦BC, and so that AP,BQ and CR are concurrent cevians. Extend the line segment RQ to meet sideline BC at point S(see figure below.) Prove that xz=y(x+y+z) where x=BP,y=P C,z=CS.(Hint: Use Ceva’s and Menelaus’ theorems.)

Given AABC, let P, Q, and R be points on sides BC, AC, and AB, respectively, with
RQ { BC, and so that AP, BQ and CR are concurrent cevians. Extend the line segment RQ to
meet sideline BC at point S (see figure below.) Prove that xz = y(x + y + z) where x = BP,
y = PC, z = CS. (Hint: Use Ceva's and Menelaus' theorems.)
