What does it mean for a circle or a triangle to be circumscribed , circumscribing , inscribed , inscribing etc.

Dear Student,

 

 

In geometry, the circumscribed circle or circumcircle of a polygon is a circle which passes through all the vertices of the polygon. The center of this circle is called the circumcenter.

 

 

 

In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is called the triangle's incenter.

 

 

 

Hope this clears the concept.
