... people. The same holds true for similar triangles (or other polygons for that matter). One way to think about similar triangles is two triangles that are not identical but do balance each other nicely. Thus, you will see similar triangles used extensively in art and architecture. Balance and proport ...

... to OG, and OG is congruent to OF, so all four of these perpendicular segments are congruent. So, since E, H, G, and F are all the same distance from O, a circle with center O containing these points exists. Furthermore, because the four sides of the kite meet radii of this circle at right angles, by ...

Rational trigonometry

Rational trigonometry is a proposed reformulation of metrical planar and solid geometries (which includes trigonometry) by Canadian mathematician Norman J. Wildberger, currently an associate professor of mathematics at the University of New South Wales. His ideas are set out in his 2005 book Divine Proportions: Rational Trigonometry to Universal Geometry. According to New Scientist, part of his motivation for an alternative to traditional trigonometry was to avoid some problems that occur when infinite series are used in mathematics. Rational trigonometry avoids direct use of transcendental functions like sine and cosine by substituting their squared equivalents. Wildberger draws inspiration from mathematicians predating Georg Cantor's infinite set-theory, like Gauss and Euclid, who he claims were far more wary of using infinite sets than modern mathematicians. To date, rational trigonometry is largely unmentioned in mainstream mathematical literature.
