ABCD is ||gm
so AB||CD
so sum of angle between these two will be 180
But due to angle bisectors sum of angles became 90
So in triangle AOD angle AOD=90°

aod =half of 180
as we know opposite angles are equal and it forms a linear pair but in a parallelogram diagnols are angular bisectors so 1/2*180=90 degrees
