History of Science and Engineering Annotation << Back ON THE TASKS TO BUILD THE GEOMETRY IN SCHOOL TEXTBOOKS IN RUSSIA IN THE 18TH CENTURY I.V. Proyaeva, A.N. Kolobov This article discusses one of the most pressing and complex issues of geometry-elements of the theory of geometric constructions. The history of various methods and techniques for solving tasks of building dates back more than two thousand years. At present, the problems of learning geometry students once again come to the fore. The authors focus on the history of the development of the theory of geometric constructions, analyzing textbooks on geometry in Russia in the 18th century. Identifi es and describes the characteristics of data entry concepts. Considerable attention is paid to the methodological Diagram solution of tasks on the plane. The information provided in the article history of the introduction of the basic concepts of the theory of geometric constructions in school course geometry was considered in particular the educational process at lectures and practical lessons on geometry at the University with students in course History Mathematics and has improved the efficiency of absorption of the studied material.
