Circle by Three PointsCircle by Three PointsThis 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. SynopsisSelect three points. Then their circumcircle is constructed. CautionThis mode is available only in Euclidean geometry. In other geometries (hyperbolic, elliptic) there is no unique circle with this property.
