WebIn general, the answer is no. However, all cyclic quadrilaterals ( quadrilaterals that can have a circumscribed circle drawn) do have opposite angles that add up to 180 degrees. It is a special property of those quadrilaterals, and it can be used to prove that a quadrilateral is cyclic. Comment ( 10 votes) Upvote Downvote Flag more Show more...
