The adjacent leg is the other side that is adjacent to angle A.The applicability to non-right-angle triangles exists, but, since any non-right-angle triangle (on a flat plane) can be bisected to create two right-angle triangles, most problems can be reduced to calculations on right-angle triangles.

A common use of mnemonics is to remember facts and relationships in trigonometry.With these functions, one can answer virtually all questions about arbitrary triangles by using the law of sines and the law of cosines.The 3rd-century astronomers first noted that the lengths of the sides of a right-angle triangle and the angles between those sides have fixed relationships: that is, if at least the length of one side and the value of one angle is known, then all other angles and lengths can be determined algorithmically.Trigonometry is most simply associated with planar right-angle triangles (each of which is a two-dimensional triangle with one angle equal to 90 degrees).### Algebra | Define Algebra at Dictionary.com

Many people find it easy to remember what sides of the right triangle are equal to sine, cosine, or tangent, by memorizing the word SOH-CAH-TOA (see below under Mnemonics ).One exception to this is spherical trigonometry, the study of triangles on spheres, surfaces of constant positive curvature, in elliptic geometry (a fundamental part of astronomy and navigation ).This formula states that if a triangle has sides of lengths a, b, and c, and if the semiperimeter is.Trigonometry, by Michael Corral, Covers elementary trigonometry, Distributed under GNU Free Documentation License.Arithmetic, algebra, geometry, trigonometry and calculus lessons.The reciprocals of these functions are named the cosecant (csc or cosec), secant (sec), and cotangent (cot), respectively.
