# Inscribed Shapes

Many geometry problems deal with shapes inside other shapes. For example, circles within triangles or squares within circles.

The inner shape is called "inscribed," and the outer shape is called "circumscribed."

When a circle is inscribed inside a polygon, the edges of the polygon are tangent to the circle.
