Answer:
Step-by-step explanation:
Given that quadrilateral ABCD inscribed in a circle
We have angle A and C are lying on either side of the centre.
If O is the centre, we get
AOC will be 2A (as per subtended arc theorem)
Similarly AOC major arc would be 2C
Since 2A+2C = 360(angle around a point)
dividing by 2, we get A+C =180
Or A and C are supplementary
Similarly we can prove B and D are supplementary.
