How to master stereometry?

polyhedron stereometry

In geometry the section which deals with three-dimensional figures is called stereometry. The word “stereometry” comes from Ancient Greece and is derived from the word “stereos”, which means “solid”, and the word “metreo”, which means “to measure”.

 

Some argue that it is hard to study stereometry since many people have problems with spatial imagination.

In reality this assumption is completely wrong. Every person obtains the ability to imagine three-dimensional figures, mentally move and transform them as we all live in a three-dimensional space. However, not everyone can apply this ability while studying stereometry; in other words, it is hard for some people to apply their everyday life experience into the studying process. This is partly due to the fact that stereometric images are made on a flat surface of paper or board.

The time when we will be able to work with books on stereometry, which would let us work with spatial images, change their position in space, transform, create new objects etc., has yet to come. 
While studying and making paper models of polyhedra you will obtain the skills of transforming flat figures into three dimensional ones. With more practice you will be able to disassemble spatial figures into more simple and plain ones. In other words, if you see an object in the real world, you will be able to create its model on paper and then make a copy of any three dimensional object.
