Features of Creation and Application Computer Animation in Geometry Teacing (Using the Manim Library as an Example)

Recently our country has focused on the increasing role of mathematical knowledge in scientific and technological progress and strengthening Russia's sovereignty. In this regard the government demands an improvement in the quality of mathematics teaching in schools. Solving this problem requires a comprehensive methodological understanding. The relevance of the research topic is determined by the growing possibilities of digital educational platforms in the learning process and data visualization. The article is devoted to the use of computer animation as an element of a new digital learning technology in the study of geometry, the development of spatial and imaginative thinking of the learner. Experts and educators believe that using dynamic visualization of educational material is more effective than static, so math teachers face a rather difficult task – creating educational content that will allow them to visualize the solution of geometric problems. Computer animations, which have great capabilities at the current stage of information tech-nology development, can help solve this problem. The most popular tools for creating mathematical animations include the Manim library of the high-level Python programming language. The purpose of the article is to examine the features of creating and using computer animations in geometry teaching using the Manim library, and to identify its advantages and disadvantages. The paper presents program codes for creating geometric shapes, and illustrates the proof of the nine-point circumference theorem using the Manim library. The article will be useful for both beginners and experienced math teachers.
