✗ Wrong: All parallelograms have 90° angles
✓ Right: Only rectangles and squares have 90° angles
✗ Wrong: Rhombus = tilted square (so has 90° angles)
✓ Right: Rhombus has equal sides but NOT necessarily 90° angles
✗ Wrong: Forgetting that a square IS a special rhombus, rectangle, and parallelogram
✓ Right: Shapes can belong to multiple categories!
