In a ΔABC, E and F are the mid-points of AC and AB respectively. The altitude AP to BC intersects FE at Q. Prove that AQ = QP.
Given : In ΔABC, E and F are the mid-points of AC and AB respectively. EF are joined. AP⊥BC is drawn which intersects EF at Q and meets BC at P.
E and F are the mid points of AC and AB
∴EF||BC and EF=12BC
∴∠F=∠B
In ΔABP,
F is mid point of AB and Q is the mid point of FE or FQ || Bc
∴ Q is mid point of AP,
∴ AQ = QP
