Non-standard geometry tasks for grades 7-11

The proposed allowance complies with the program in mathematics for general education institutions. It contains about 500 non-standard and research tasks on geometry of various levels of difficulty. The solution of such tasks has a large developing and educational significance for students. They contribute to the development of thinking, its certain style, culture, form geometric representations, skills of independent and research work, contribute to a deeper understanding of geometry. During the search for non-sterootic tasks, realization, ingenuity, seducker and others are developing, is very useful in the life of every person. For convenience, the content of the collection is divided into separate items, there are only 34 of them, and they first propose tasks for planimetry, and then according to stereometry. All major topics of the geometry of the main school and senior classes are considered. At the end of the manual, there are answers and solutions to all considered tasks.
