Geometry, Tasks and exercises on ready drawings, 7-9 class, Rabinovich EM, 2010. The proposed manual is an additional collection of problems in geometry for students of grades 7-9 and is oriented to AV Pogorelov's textbook 'Geometry 7-11 '. The manual is compiled in the form of tables and contains more than 400 tasks and exercises on geometry for pupils of grades 7-9. The tasks of each table correspond to a certain topic of the school planimetry course. In the manual 13 tables for the 7th grade, 17 tables for the 8th class and 14 tables for the 9th grade. It is intended primarily for teaching students how to solve problems independently of the material they have just studied.
Tasks can also be used to organize independent and testing works. Many assignments can be resolved verbally. Most of the tasks and exercises are given answers, directions and solutions. Regular polygons a - the side of the regular polygon, R (r) - the radius of the circumscribed (inscribed) circle, O - the center of the regular polygon. Knowing the number of sides of a regular polygon Knowing one of the elements (a, R or r), find the other two Measurement of the segments Given: AB = 6 cm, BC = 9 cm. Given: MP = 12 cm, CD = 3 cm. Given: DF = 9.3 cm.
Find the error. 1) Given: AB = CD. Prove: AC = BD.
2) Given: AC = BD. Prove: AB = CD. Table of Contents Foreword Class 7 7.1. Measurement of segments 7.2. Measurement of angles 7.3. Adjacent Angles 7.4.
