This is a quite difficult problem. First of all we need to calculate all angle relations. Then we need to take into account rotations and reflections - in this way we have only non-similar quadrilaterals. Finally we have to pick those angles that satisfie given order condition.

what does this means Note: In your calculations you may assume that a calculated angle is integral if it is within a tolerance of of an integer value.
and what difference does it makes
Can anybody explain me about this ai<=bi and 1<=bi<=180,bi<=bi+1
i can't understand this line, "What is the number of non-similar integer angled quadrilaterals such that ai <= bi ?"
