The role of drawing in geometric arguments

From the distant times, understanding and understanding the concepts of mathematics and geometry for most students and students has been an acute problem. In particular, understanding the concepts of geometry, which is associated with spatial visualization, makes the problems of understanding and learning double. Geometry and polygons, in particular, are one of the important tools that can help eliminate these ambiguities. In the process of teaching-learning in the subject of geometric drawings and reasoning, there are many factors and elements involved, the teacher has to organize this set of factors in order to positively influence his class, so that he will use all the tools and professional knowledge he possesses to maximize his use. Takes. To take advantage of them, teachers must have different thinking skills. Thoughtful action of teachers plays a key role in improving the quality of teaching and learning in class. The study of Thales's theorem and similarity in geometric shapes are of great importance. In this paper, the basic concepts of geometry are considered. Then, using the drawing tool, problems that are obscure for students or learners are answered.
