Answer:

  The quadrilateral is an isosceles trapezoid.

Step-by-step explanation:

If we call the ends of the first arc A and B, and the ends of the second arc C and D (listed in the clockwise direction), then the following will be true:

  • BC will be parallel to AD
  • angles B and C will be congruent, as will angles A and D
  • diagonals AC and BD will be congruent
  • the perpendicular bisector of BC is the same line as the perpendicular bisector of AD. Said line is a line of symmetry for the quadrilateral.

All of these observations are consistent with ABCD being an isosceles trapezoid.
