The converse of a conditional statement is "If the sum of the exterior angles of a figure is 360°, then the figure is a polygon.”What is the inverse of the original conditional statement?

If a figure is a polygon, then the sum of the exterior angles is 360°.

If the sum of the exterior angles of a figure is not 360°, then the figure is not a polygon.

If the sum of the exterior angles of a figure is 360°, then the figure is not a polygon.

If a figure is not a polygon, then the sum of the exterior angles is not 360°.
