Circle by Three Points


This mode is for constructing a circle that passes through three points. In Euclidean geometry such a circle is always uniquely defined to be the circumcircle of the triangle defined by the three points. You choose the points one after another. The definition phase does not supply graphical hints.


Synopsis


Select three points. Then their circumcircle is constructed.



Caution


This mode is available only in Euclidean geometry. In other geometries (hyperbolic, elliptic) there is no unique circle with this property.
