different between trigonometry vs triangulation
trigonometry
English
Etymology
From 1610s, from New Latin trig?nometria, from Ancient Greek ???????? (tríg?non, “triangle”) + ?????? (métron, “measure”).
Pronunciation
- IPA(key): /?t?????n?m?t?i/
Noun
trigonometry (countable and uncountable, plural trigonometries)
- (geometry, mathematical analysis) The branch of mathematics that deals with the relationships between the sides and angles of (in particular) right-angled triangles, as represented by the trigonometric functions, and with calculations based on said relationships.
- 1892, Edward Albert Bowser, A Treatise on Plane and Spherical Trigonometry, D. C. Heath & Co., page 1,
- Trigonometry was originally the science which treated only of the sides and angles of plane and spherical triangles; but it has been recently extended so as to include the analytic treatment of all theorems involving the consideration of angular magnitudes.
- 2013, Paul Abbott, Hugh Neill, Trigonometry: A Complete Introduction, Hachette, unnumbered page,
- In fact, the earliest practical uses of trigonometry were in the fields of astronomy and hence navigation.
- 2016, Carl F. Lorenzo, Tom T. Hartley, The Fractional Trigonometry, Wiley, page 8,
- The properties of these new trigonometries and identities flowing from the definitions are then developed.
- The trigonometries derived from these generalizations will be jointly termed "The Fractional Trigonometry."
- 1892, Edward Albert Bowser, A Treatise on Plane and Spherical Trigonometry, D. C. Heath & Co., page 1,

- (branch of mathematics): trig (informal, abbreviation)

triangulation
English
Etymology
From Medieval Latin triangul?ti?nem (“triangulation”), from triangul?re (“to triangulate”) + -ti?nem (suffix forming nouns relating to some actions or the results of actions). Triangul?re is derived from triangul?ris (“triangular”), from triangulus (“triangular; triangle”), from tr?s (“three”) + angulus (“angle; corner”). The English word is analysable as triangulate +? -ion, and is cognate with French triangulation.

Noun
triangulation (countable and uncountable, plural triangulations)
- (uncountable, surveying) A technique in which distances and directions are estimated from an accurately measured baseline and the principles of trigonometry; (countable) an instance of the use of this technique.
- (countable, surveying) The network of triangles so obtained, that are the basis of a chart or map.
- (countable, chess) A delaying move in which the king moves in a triangular path to force the advance of a pawn.
- (countable, geometry) A subdivision of a planar object into triangles, and by extension the subdivision of a higher-dimension geometric object into simplices.
- (uncountable, navigation, seismology) A process by which an unknown location is found using three known distances from known locations.
- (uncountable, politics) The practice of repositioning one's group or oneself on the political spectrum in an attempt to capture the centre.
- (uncountable, qualitative research) The use of three (or more) researchers to interview the same people or to evaluate the same evidence to reduce the impact of individual bias.
