In a `triangleABC` P and Q are points on AB and AC respectively and PQ||BC. Prove that the median AD bisects PQ.

ABC is a triangle A line is drawn parallel to BC to meet AB and AC in D and E respectively. Prove that the median through A bisects DE.

In triangle ABC , P and Q are the middle points of the sides AB and AC respectively. R is a point on the segment PQ such that PR: RQ =1: 2. If PR = 2cm, then BC =? triangle ABC में, P और Q क्रमशः भुजाओं AB तथा AC के मध्य बिंदु हैं। R, PQ पर एक बिंदु इस प्रकार है कि PR: RQ =1: 2 यदि PR=2 सेमी, तो BC=

If DE||BC in triangleABC where D and E are points on AB and AC respectively. If (AD)/(DB) = 8/15 and EC = 3.5 cm , find AE.

ABC is an equilateral triangle. P and Q are two points on bar(AB) and bar(AC) respectively such that bar(PQ) || bar(BC) . If bar(PQ) = 5cm , then area of Delta APQ is :

In Delta ABC, P,Q and R are midpoints of sides AB,AC and BC respectively. Seg AS _|_BC and PQ || BR side BC. Prove that square PQRS is a cyclic quadrilateral.

If P and Q are points on the sides AB and AC respeactively of triangleABC , if PQ||BC,l AP= 2 cm , AB = 6 cm and AC= 9 cm find AQ.
