Tasks for solid geometry

Треугольная пирамида

task 1

The figures show the sweep of the pyramid ABCD dividing point it is necessary to identify these letters so as to obtain a triangular pyramid.
Without the help of models of these tasks are useful for everyone. They develop imagination and logical thinking. Such problems can be solved without the help of knowledge. If the solution does not work, then scan the model suggests a solution. The aforementioned main modifications pyramid, but opportunities are endless transformations. The simplicity of the device and versatility action opens an interesting and complex world of geometry, so the pyramid need to have on the table the student in the classroom

геометрии.
