What children learn in Level 87
- All these shapes have 4 sides. What sets them apart? A parallelogram has 2 pairs of parallel sides.
- A rectangle is a parallelogram with 4 right angles.
- A rhombus is a parallelogram with 4 equal sides.
- A square has both: 4 right angles and 4 equal sides. So a square is a rectangle, a rhombus, and a parallelogram, all at once!
