    Hello Raj

    Let ABCD be the quadrilateral.

    Given Sum of two angles is two right angles

    So, ∠ A + ∠ B = 180

     

    Now, we know that

    Sum of angles of quadrilateral is 180

    So,  ∠ A + ∠ B +∠ C + ∠ D = 360

     (∠ A + ∠ B) +∠ C + ∠ D = 360

    180 +∠ C + ∠ D = 360

    ∠ C + ∠ D = 360 - 180

    ∠ C + ∠ D = 180

     

    So, sum of other two angles is 180
