Sum of the angle in a triangle is 180 degree. a) The triangle BCOis an isosceles triangle. An interpretation of it was certainly known at least a millennium befor e Thales' time in Mesopotamia, and it is possible that some interpretation of it was known in Egypt, but my argument is that the case for Thales' Exercise: The picture we drew was too nice. What is the ratio of the areas of two similar (homothetic) figures? appearances are structured. Thales' intercept theorem (not to be confused with another theorem with that name, which is a particular case of the inscribed angle theorem) is an important theorem in elementary geometry about the ratios of various line segments that are created if two intersecting lines are intercepted by a pair of parallels.
