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
