ABCD is a parallelogram of area "S". E and F are the mid points of the sides AD and BC respectively. If G is any point on the line EF. then the area of ΔAGB is equal to

ABCD is a quadrilateral in which P, Q, R and S are mid-points of the sides AB, BC, CD and DA (see Fig 8.29). AC is a diagonal. Show that:(i) SR || AC and SR = 1/2 AC(ii) PQ = SR(iii) PQRS is a parallelogram.

Quadrilateral ABCD has diagonals AC and BDWhich information is not sufficient to prove and ABCD is a parallelogram?Group of answer choicesAB is congruent to CD and AB is parallel to CDAB is congruent to CD and BC is congruent to ADAC and BD bisect each otherAB is congruent to CD and BC is parallel to AD

If angles A, B, C and D of the quadrilateral ABCD, taken in order, are in the ratio 3:7:6:4, then ABCD is
