Abstract :This paper sheds more lights on finding out a new methodology in teaching Thales theorem results and working with fractions in similarity to help students analyze Thales theorem and come up to some solutions with solving any problems related to the pieces of Cross Chords of Circle, Right Triangle and Right Trapezoid. In this regarding, I have come to a conclusion, from fourteen years of teaching experience in mathematics to Iranian high school students, that the best way could be starting from theorem statements to hypotheses as well as using properties of fractions. Therefore, in this study pre test-post test experimental design with control group was used and sample of the study was composed of 44 Iranian second graders at high school. It was concluded that meaningful differences in favor of experimental group and success in pre test-post test comparisons were obtained.
