Question

Jeff constructed a square inscribed in a circle:EFFDWhich provides enough justification to prove that CDEF is a square?All four angles of the quadrilateral are 90°.All four sides of the quadrilateral are congruent.O Opposite sides of the quadrilateral are parallel.The diagonals of the quadrilateral are perpendicular and congruent.

Answer 1

A square is a quadrilateral with four equal straight sides and four right angles.

In this sense since the diagonals of a square bisect each other and meet at 90° and are congruent, we can conclude it is enough justification to prove that CDEF is a square
