[quote=mohammad.ashtari;332920]Hi all,

I have a triangle in 3d space which I know the coordinates for two of its vertices A(1,2,3) and B(-1,-2,-3). I also know all the angles of the triangle and all the AB, AC and BC lengths. How can I find the x, y and z coordinates for the last vertex ?


my friend first u should tell me what r th angles then we can do something ..........



thnks in advance
