Shapes are fundamental elements in geometry, representing the form of objects in space. They can be classified into various categories, such as 2D shapes and 3D shapes. Common examples of 2D shapes include circles, squares, and triangles, each defined by specific properties like the number of sides and angles. In addition to their mathematical significance, shapes play a crucial role in art and design. Artists often use shapes to create visual compositions, while designers rely on them to develop functional and aesthetic products. Understanding shapes enhances our ability to interpret and interact with the world around us.
