Explanation of trigonometry
WebIn a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. Webtrigonometry ( ˌtrɪɡəˈnɒmɪtrɪ) n (Mathematics) the branch of mathematics concerned with the properties of trigonometric functions and their application to the determination of the angles and sides of triangles. Used in surveying, navigation, etc. Abbreviation: trig [C17: from New Latin trigōnometria from Greek trigōnon triangle]

WebMar 14, 2024 · trigonometry: [noun] the study of the properties of triangles and trigonometric functions and of their applications. WebTrigonometry functions of large and/or negative angles. The six functions can also be defined in a rectangular coordinate system. This allows them to go beyond right triangles, to where the angles can have any measure, even beyond 360°, and can be both positive and negative. For more on this see Trigonometry functions of large and negative angles.
