NOTE 2: The Angle Side Side theorem (yes, we all know what it spells) does NOT necessarily work. Triangles with the same degree measures are similar and their sides will be in the same ratio to each other. This is equivalent to the statement that each line from a triangle's circumcenter to a vertex is always perpendicular to the corresponding side of the orthic triangle (Honsberger 1995, p. Calculations at a general, convex quadrilateral or quadrangle. Hence BD is the geometric mean of AD and DC. Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles. Entering sides of values 1. An equilateral triangle has all sides equal and each interior angle is equal to 60°. Similarity between triangles is the basis of trigonometry, which literally means triangle measure.
