How to construct Inscribed and Circumscribed Circles using incenter, circumcenter, or centroid?
The following diagram shows how to construct a circle inscribed in a triangle. Scroll down the page for more examples and solutions on circumscribed and inscribed circles.
Circumscribed and Inscribed Circles
A circle is circumscribed about a polygon if the polygon's vertices are on the circle. For triangles, the center of this circle is the circumcenter.
A circle is inscribed a polygon if the sides of the polygon are tangential to the circle. For triangles, the center of this circle is the incenter. Circumscribed and inscribed circles show up a lot in area problems.
