    Hi samar! :smile:

    The circumcircle of a triangle is the unique circle which goes through all three vertices.

    Obviously, it is the smallest circle which can contain the whole triangle.

    (Not to be confused with the in-circle, or inscribed circle, which is the unique circle whch touches all three sides of the triangle, from the inside, and which is the largest circle which can be contained inside the triangle.!)

    For more information, see: http://en.wikipedia.org/wiki/Circumcircle#Circumcircles_of_triangles
