Quadrilaterals ...

The length of each side of a rhombus is 10cm and one of its diagonal is of length 16cm. The Length of the other Diagonal is:

If ABCD is a Parallelogram with 2 Adjacent angles ∠A=∠B, then the parallelogram is a

If an angle of a parallelogram is two-third of its adjacent angle, the smallest angle of the parallelogram is:

If area of a Parallelogram with sides ‘a’ and ‘b’ is A and that of a rectangle with sides ‘a’ and ‘b’ is B, then

The Parallel sides of a trapezium are ‘a’ and ‘b’ resp. The line joining the mid-points of its non-parallel sides will be

Two parallelograms stand on same base and between the same parallels. The ratio of their areas is

Three Statements are given below:
(I) In a, Parallelogram the angle bisectors of 2 adjacent angles enclose a right angle.
(II) The angle bisector of a Parallelogram form a Rectangle.
(III) The Triangle formed by joining the mid-points of the sides of an isosceles triangle is not necessarily an isosceles triangle.
Which of the statement/statements is/areTrue?

Three statements are given below:

1. In a Rectangle ABCD, the diagonals AC bisects ∠A as well as ∠C.
2. In a Square ABCD, the diagonals AC bisects ∠A as well as ∠C.
3. In rhombus ABCD, the diagonals AC bisects ∠A as well as ∠C.

Which is True?

In a triangle ABC, P, Q and R are the mid-points of the sides BC, CA and AB respectively. If AC = 21cm, BC = 29cm and AB = 30cm, find the perimeter of the quadrilateral ARPQ?

If a Quadrilateral ABCD, ∠A = 90^∘ and AB = BC = CD = DA, Then ABCD is a
