how to get the vertex of a triangle after rotation
Which one? A triangle has 3 vertices (hence the tri-)
i knew there is a function glFloatv
No, there isn't. Maybe you're confusing it with glGetFloatvf. However the glGet… functionsare are meant for retrieving OpenGL state variables, not giving transformation feedback.
If you've got only hand full of triangles to process, use gluProject
