One Application of the Informatics in the Descriptive Geometry

This work acquaints with a program for interactive computer training to students on the subject "Mutual intersecting of pyramids in axonometry ”. Our software is a set of three modules, which we call "student", "teacher" and "autopilot". It gives the final solution of the problem, the traceability of various significant moments in its solution and 3D-image of the finished composition of the two intersecting polyhedra, stripped of the working lines and subjected to rotation and translation.

Характеристични свойства на някои многостени

Plamen Penchev - The origin is a problem from the Canadian Mathematical Olympiad in 1980, which is solved in general and ended to similar variants. Certain characteristic properties of such polyhedra are investigated.
