Two types of trigonometry are recognized: planar and spherical. Planar is 2-dimensional, while spherical is 3-dimensional. Though these are different fields, spherical trigonometry is really just an application of planar trigonometry in several planes.
"Trigonometry" comes from the Greek words trigonon and metron, and roughly translates to "the measurement of angles".
From Greek.Trigon comes from 3-sided figure, now known as a triangle. Metry comes from measurement.
comes from three Greek words; "tria"-three, "gonia"-angle, "metron"-measurement RAYMARK is online
The word trigonometry comes from two Greek words, trigonon, meaning triangle, and metria, meaning measurement. This is the branch of mathematics that deals with the ratios between the sides of right triangles with reference to either of its acute angles and enables you to use this information to find unknown sides or angles of any triangle. Trigonometry is not just an intellectual exercise, but has uses in the fields of engineering, surveying, navigation, archicecture, and even rocket science.
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
There are more than two but the two most common ones are plane trig and spherical trig.
Trigonometry is a branch of geometry which is primarily concerned with the properties and measurement of triangles.
Two types of trigonometry are recognized: planar and spherical. Planar is 2-dimensional, while spherical is 3-dimensional. Though these are different fields, spherical trigonometry is really just an application of planar trigonometry in several planes.
Angular displacements measured in radians or stradians, lengths of lines measured in units of length.

trigon = triangle metry = measurement.

'Trigonometry' comes from Greek: 'trigonon' = 'triangle' and 'metron' = 'measure'. So, basically, the measurement of triangles.
The side that the measurement of an angle starts from.
Right, acute, and obtuse...
From Greek: tri = threegon = corner metry = measurement.
