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.

Keywords
