Developing mathematical thinking and reasoning ability for students through teaching the chapter of angle with circuit – 9th grade Geometry.

Abstract

The article proposes a number of measures to develop students’ ability to think and reason mathematically through teaching the corner chapter with circles-Geometry 9, including: Practice for students to perform operations thinking analytically, synthesizing in the process of learning concepts, proving theorems or solving exercises on corners with circles; Train students in the operations of comparison, analogy, generalization, and specialisation in the process of solving exercises of the corner chapter with the circle; Guide students to analyze and argue from different angles to find many different solutions while solving the corner chapter exercises with circles.
