Square vs Rhombus: Analyzing Geometric Properties of a Given Square

To solve this problem, we'll consider the definitions:

• A square is a quadrilateral with four equal sides and four equal angles (each angle is $90$ degrees).
• A rhombus is a quadrilateral with all sides equal in length.

Notice that for a quadrilateral to be a rhombus, it simply requires all sides to be equal, without any condition on the angles. Since a square has all four sides equal, it meets the fundamental requirement of a rhombus.

Therefore, every square can be classified as a rhombus because it satisfies the condition that all sides are equal.

Hence, the correct answer is Yes, the square is a rhombus.
