Introduction to oblique projection

This master thesis briefly sumarizes the basic knowledge of oblique projection in according with high schools curriculum. For example there are positional tasks, construction of planar shapes and solids or solution of easy solid sections. This thesis preceded questionnaire finding out parts of oblique projection which are taught during descriptive geometry at high schools. Other tasks with step by step solution have been created at the same time. Tasks are available at geogebra.org. The CD with sources file of images is included in this work. This text can help students at high school or teachers of descriptive geometry
