In the figure ABCD is a rectangle and diagonals intersect at O. If , find .

The adjoining figure is a rectangle whose diagonals AC and BD intersect at O. If ∠OAB = 27°, then find ∠OBC.

b. It is known that the diagonals of this rectangle bisect each other at the point of intersection. Using this fact, check (using appropriate calculations) whether the diagonals are perpendicular to each other.

The diagonals of rectangle ABCD intersect at a point O. If ∠COD is 78°, then find ∠OAB.

Assertion : ABCD is a square. AC and BD intersect at “O “. The measure of ∠ AOB= 90°.Reason : Diagonals of a square bisect each other at right angles.

n the given figure ABCD is a rhom
