In what way is a square compared to a rectangle?

A square is considered similar to a rectangle because both shapes belong to the category of quadrilaterals, which are figures that have four sides. The defining characteristic of a square is that all four of its sides are of equal length, and all its angles are right angles. A rectangle, on the other hand, has opposite sides that are equal in length, with all angles also being right angles. Therefore, every square is a rectangle since it meets the criteria of having four right angles and opposite sides being equal, but not all rectangles are squares because they do not have to have equal-length sides. This similarity highlights the relationship between the two shapes, as they share fundamental properties while also having distinct differences.
