Inscribed shapes are geometric figures that are drawn within another shape, where all vertices of the inscribed shape touch the boundary of the outer shape. For example, a triangle can be inscribed within a circle, with each vertex of the triangle touching the circle's circumference. This concept is often used in geometry to explore relationships between different shapes. The process of inscribing shapes helps in understanding properties such as area and perimeter. For instance, the area of an inscribed polygon can be calculated using the radius of the outer circle. Inscribed shapes are commonly studied in various fields, including mathematics and architecture.
