Why a square is a rectangle but a rectangle is not a square?

Answer 1

A rectangle is a plane four sided shape. It has two pairs of parallel sides which meet at right angles. So is a square. The opposite sides of a rectangle are equal but in a square all four sides are equal. So a square is a rectangle but a rectangle is not a square.

Answer 2

A square is a special type of rectangle where all four sides are equal in length. A rectangle is defined as a four-sided shape with opposite sides being equal and all interior angles measuring 90 degrees. Since a square meets the criteria of a rectangle (opposite sides are equal and angles are 90 degrees), it can be classified as a rectangle. However, a rectangle that does not have all sides equal cannot be classified as a square because a square has an additional requirement of all sides being equal.

Answer 3

Well, honey, a square is a type of rectangle because it has four right angles and opposite sides that are equal. But not all rectangles can be squares because squares have all sides of equal length, while rectangles can have different side lengths. It's like saying all squares are rectangles, but not all rectangles are squares. Clear as crystal, right?
