Square and Rectangle
A square and a rectangle are two flat shapes that children see every day. Both have 4 sides and 4 corners. They look similar, but there is one important difference.
A square has all 4 sides equal. A rectangle has opposite sides equal — two longer sides and two shorter sides. Both shapes have straight sides and square corners.
