Shape properties refer to the characteristics that define different geometric shapes. These properties include attributes such as the number of sides, angles, and symmetry. For example, a triangle has three sides and three angles, while a square has four equal sides and four right angles. Understanding these properties helps in identifying and classifying shapes. Additionally, shape properties can influence how shapes interact with one another. For instance, the perimeter is the total distance around a shape, while the area measures the space inside it. Recognizing these properties is essential in fields like mathematics, architecture, and design.
