The proposed elective course contains an overview, generalization and systematization of the theoretical and task material of the school planimetry course in order to qualitatively prepare students in grades 9 and 11 for the final certification in mathematics (OGE, USE). The manual is addressed to high school students and teachers to provide assistance in highlighting the main types of tasks and leading methods for solving them, in practicing the skills of using supporting facts in solving planimetry problems, as well as in organizing independent activities of students in preparation for practices and tests in solving planimetric problems.
