{"type":"rich","version":"1.0","description":"Players match formal statements about parallelograms and rectangles to the theorem or converse they represent, focusing on recognizing the exact meaning of key geometric results used in proofs. This includes proving theorems about parallelograms: opposite sides and angles are congruent, diagonals bisect each other, and that rectangles are parallelograms with congruent diagonals.
