Geometry Level pending

Two right isosceles triangles are inscribed in a quadrilateral. Their right angles are at opposing vertices of the quadrilateral. Their other vertices are midpoint of its sides. Find the largest angle of the quadrilateral.

Details:$$AF=FB,BG=GC,CH=HD,DE=EA$$

$$\angle ECF=90^\circ, \angle HAG=90^\circ, AH=AG, CE=CF$$
