Lesson 30: trigonometry and the pythagorean theorem student outcomes the language in gsrt8 juxtaposes trigonometric ratios and the pythagorean theorem in the same standard, which leads directly to the pythagorean identity for right triangles. The sum of the squares of the other two sides euclid's proof is much more complex, and relies on subdividing a figure into pieces and showing that they are congruent pieces it's a fragment of mathematical history you do not need to remember this proof in fact if it's the first time you're. The trigonometric ratios are the angles of the cos, sin and tan also known as the cosine sin and tangent history behind trigonometric ratios the history of trigonometry dates back to the early ages of egypt and babylon angles were then measured in degrees history of trigonometry was then advanced.
