Race, Ethnicity & Nationality. We have already discussed a few example of trig identities. All identities are meant to serve as examples of equality. Convert one expression into another. Can be used to verify relationships or simplify expressions in terms of a single trig function or similar. If triangles are similar are other things similar as well. Proportional Parts Conjecture. If two triangles are similar, then the length of the corresponding altitudes, medians, and angle bisectors are proportional to the lengths of the corresponding sides. This shows similar Triangles.

Peter Heath: "An inveterate publisher of trifles [who] was forever putting out pamphlets, papers, broadsheets, and books on mathematical topics [that] earned him no reputation beyond that of a crotchety, if sometimes amusing, controversialist, a compiler of puzzles and curiosities, and a busy yet ineffective reformer on elementary points of computation and instructional method. In the higher reaches of the subject he made no mark at all, and has left none since." . Chapter 4. This Slideshow was developed to accompany the textbook. Larson Geometry.
