Question

A circle could be circumscribed about the quadrilateral below true or false?

Answer 1

The answer is false.
Hope this helps.

Answer 2

If opposite angles of a quadrilateral add to 180 then it is called a cyclic quadrilateral and a circle can be inscribed in it. Here, the opposite sides are 115 and 65 (=180), and 90 and 90 (=180), which means that it is true that a circle can be circumscribed about the quadrilateral above.
