ABCD is a quadirlateral in which AD= BC. If P,Q,R,S be the midpoints of AB,AC,CD and BD respectively, show that PQRS is a rhombus.

ABCD is a quadrilateral in which AD = BC. E, F, G and H are the mid-points of AB, BD, CD and AC respectively. Prove that EFGH is a rhombus.

ABCD is a quadrilateral in which P,Q,R and S are the mid points of sides AB,BC,CD and DA respectively AC is a diagonal show that: PQRS is a parallelogram.

ABCD is rectangle formed by the points A(-1, -1), B(-1, 4), C(5, 4) and D(5, -1). If P, Q, R and S be the midpoint of AB, BC, CD and DA respectively, show that PQRS is a rhombus.

ABCD is a quadrilateral in which P,Q,R and S are the mid points of sides AB,BC,CD and DA respectively AC is a diagonal show that: PQ=SR

ABCD is a quadrilateral in which P,Q,R and S are the mid points of sides AB,BC,CD and DA respectively AC is a diagonal show that: SR||AC and SR=1/2AC

ABCD is a quadrilateral in which P, Q, R and S are the mid-points of sides AB, BC, CD and DA respectively (See Fig. AC is a diagonal Show that SR II AC and SR = 1/2 AC .

ABCD is a quadrilateral in which P, Q, R and S are the mid-points of sides AB, BC, CD and DA respectively (See Fig. AC is a diagonal Show that SR II AC and SR = 1/2 AC .

ABCD is a quadrilateral in which P, Q, R and S are the mid-points of sides AB, BC, CD and DA respectively (See Fig.) AC is a diagonal Show that PQ = SR.

ABCD is a quadrilateral in which P, Q, R and S are the mid-points of sides AB, BC, CD and DA respectively (See Fig.) AC is a diagonal Show that PQ = SR.

In the fig. ABCD is a trapezium in which AB||DC and AD=BC. IF P,Q,R,S are respectively the mid points of BA,BD and CD,CA, then show that PQRS is a rhombus.
