The relation between the sides and angles of a right triangle is the basis for trigonometry.... s. Trigonometry deals with relationships between the sides and the angles of triangles, and with trigonometric functions, which describe those relationships and angles in general, and the motion of wave Wave A wave is a disturbance that propagates through space and time, usually by transference of energy. A mechanical wave is a wave that propagates through a medium due to restoring forces produced upon its deformation. For example, sound waves propagate via air molecules bumping into their neighbors....

This is a Greek letter and is pronounced phi . The angle between sides a and b is o , a right-angle . The side c , which is opposite the right angle, is called the hypotenuse (from a Greek word meaning stretch Pythagoras (c582 BC - c497 BC) proved what is now called Pythagoras' Theorem although it had been in use for centuries in the ancient world for building and measuring. The theorem can be described as follows: In a right-angles triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. This is written mathematically as a + b = c Example 1: If a right-angled triangle has smaller sides of length 3 and 4. What is the length of the hypotenuse? From Pythagoras' Theorem

Triangles on a sphere are also studied, in spherical trigonometry. Trigonometry specifically deals with the relationships between the sides and the angles of triangles, that is, the trigonometric functions, and with calculations based on these functions. Trigonometry has important applications in many branches of pure mathematics as well as of applied mathematics and, consequently, much of science.
