What is the inverse of the following conditional statement?
"If the sum of the interior angles of a polygon is $$180^\circ$$, then the polygon is a triangle."
If the polygon is a triangle, then the sum of the interior angles of the polygon is $$180^\circ$$.
If the sum of the interior angles of a polygon is not $$180^\circ$$, then the polygon is not a triangle.
If the polygon is not a triangle, then the sum of interior angles of the polygon is not $$180^\circ$$.
If the sum of the interior angles of a polygon is $$180^\circ$$, then the triangle is a polygon.
