Whatis the converse of the if a polygon has exactly four sides then it is quadrilateral​

answer is polygon is a quadrilateral, then the polygon has only four sides

Try this one, too: "If the quadrilateral has four congruent sides and angles, then the quadrilateral is a square." Converse: If the quadrilateral is a square, then the quadrilateral has four congruent sides and angles.

the solution is h=10 because you add 9 to each side of the equation.
