Judging Conditions and Computation of Circumcenter of Space Triangle
The judging conditions and computation of the circumcenter of space triangle are studied.Firstly,three important lemmas about the space triangle are given,then three sufficient and necessary conditions and three neces-sary conditions for judging the circumcenter are given by using the definition of the circumcenter and one proposi-tion.Finally,the calculation formula of the coordinates of the circumcenter of space triangles is given by using the judging conditions,so that students can have a deeper understanding and mastery of the circumcenter of space tri-angle,which provides technical support for the application of space triangle in the field of engineering technology.
