The second sentence is the contrapositive of the first sentence. In logical terms, it asserts that if a polygon does not meet the condition of having four sides, it cannot be classified as a quadrilateral. Both sentences convey the same fundamental relationship about the definition of a quadrilateral, emphasizing the necessity of having four sides for that classification.

The second sentence reiterates the relationship established in the first sentence but adds a stronger condition. The first sentence indicates that being a square implies being a parallelogram, while the second sentence specifies that the two properties are equivalent—meaning a quadrilateral is a square if and only if it is a parallelogram. This indicates a bidirectional relationship between the two concepts.
