In geometry, "circumscribed" means "to draw around." A circumscribed circle is a circle that is drawn around a polygon so that it passes through all the vertices of a polygon inscribed in it. All … [Read more...] about Circumscribed Circle

# 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.

*Now that we've explained the basic concept of inscribed shapes in geometry, let's scroll down to work on specific geometry problems relating to this topic.*

## Area of a Circle Inscribed in an Equilateral Triangle

We can use the properties of an equilateral triangle and a 30-60-90 right triangle to find the area of a circle inscribed in an equilateral triangle, using only the triangle's side … [Read more...] about Area of a Circle Inscribed in an Equilateral Triangle

## Inscribed Shapes: Finding the Length of a Radius

Many geometry problems involve a triangle inscribed in a circle, where the key to solving the problem is relying on the fact that each one of the inscribed triangle's angels is an inscribed angle in … [Read more...] about Inscribed Shapes: Finding the Length of a Radius

## Inscribed Shapes: Opposing Angles of a Quadrangle Inscribed in a Circle

Not all quadrangles can be inscribed in a circle. Intuitively, if we think of a quadrangle like this slim diamond -We can see that no circle can be drawn so that all four of its corners will … [Read more...] about Inscribed Shapes: Opposing Angles of a Quadrangle Inscribed in a Circle

## Polygon Inside a Circle

We will solve most problems involving polygons inscribed in a circle by using theorems related to inscribed angles, as the vertices of the polygons form inscribed angles.ProblemAn irregular … [Read more...] about Polygon Inside a Circle
