State whether the following statement is True or False and justify your answer: $ABCD$ is a cyclic quadrilateral such that $\angle A = 90^{\circ}, \angle B = 70^{\circ}, \angle C = 95^{\circ}$ and $\angle D = 105^{\circ}$.

(B) We know that the sum of opposite angles of a cyclic quadrilateral is always $180^{\circ}$.
In the given quadrilateral $ABCD$,let us check the sum of opposite angles:
$\angle A + \angle C = 90^{\circ} + 95^{\circ} = 185^{\circ}$.
Since the sum of opposite angles is not $180^{\circ}$,the quadrilateral $ABCD$ cannot be a cyclic quadrilateral.
Therefore,the given statement is False.
