AI overview
A square is a four-sided shape where all sides are equal in length and all corners form right angles (90 degrees). Squares matter because they're fundamental in geometry and mathematics—their properties are used to calculate area, and the concept of "squaring" a number (multiplying it by itself) is named after this shape's mathematical importance.
