Pretty interesting…I just found an extension of LaTeX - Euklides, it can draw Euclidean Geometry graph by some pretty easy language, like

A B C D parallelogram(5, 4, 105 ; draw(A, B, C, D)
mark(B, A, D) ; mark(D, C, B)
mark(C, B, A, double) ; mark(A, D, C, double)

Sound very useful for those need to wrote math exam paper for primary/secoundary school.
