PQRS is a parallelogram and its area is 300 cm^2 . Side PQ is extended to X such that PQ=QX. If XS intersects QR at Y, then what is the area (in cm^2 ) of triangle SYR? PQRS एक समांतर चतुर्भुज है तथा 300 से.मी.^2 है। भुजा को तक इस तरह बढाया गया कि PQ=QX है। यदि XS, QR को Y पर काटता है, तो त्रिसुज SYR का क्षेत्रफल ( से.मी.^2 में) क्या हैं?

In the given figure, ABCD is a parallelogram in which DC is extended to F such that AF intersects BC at E . Then perimeter of DeltaABE =

The coordinates of P and Q are (-3, 4) and (2, 1), respectively. If PQ is extended to R such that PR=2QR , then what are the coordinates of R ?

In Delta ABC , AD is a median and E is the midpoint of AD. BE is extended to intersect AC at F. Prove that AF = (1)/(3)AC .

E is a mid-point of median AD of DeltaABC . BE is extended to meet AC at F. In what ratio AC is divided by F.

PQRS is a parallelogram. If a straight line EF through S intersects PQ and extended RQ at the points X and Y respectively, then prove that PS:PX=QY:QX=RY:RS
