Answer 2

Answer:

Here ABCD is the cyclic quidrilateral and OH, OG, OF and OE are perendicular bisectors of AB, BC, CD, AD.

We know that in a perpendicular bisector of a line segment is passing through the centre.

= OH, OG, OF and OE passess through centre.

= OH, OG, OF and OE are concurrent.

Hence the perpendicular bisector of the sides of the cyclic quidrilateral are concurrent.
