They are: scalene, right angle, obtuse, isosceles and equilateral triangles
Trigonometry based on a unit circle and radians and trigonometry based on a right triangle.
the founder thinks that how to relate the perpendicular triangle's sides.so that in that way he found the trigonometry.
The basic principle of trigonometry is that there are mathematical relationships between the sides and angles of a triangle.
He defined the spherical triangle
trigon = triangle metry = measurement.
SoH: used for finding the sine of a triangle in trigonometry: Opposite/HypotenuseCaH: used for finding the cosine of a triangle in trigonometry: Adjacent/HypotenuseToA: used for finding the tangent of a triangle in trigonometry: Opposite/Adjacent
Trigonometry based on a unit circle and radians and trigonometry based on a right triangle.
triangle measure
trigonometry is actually the studies of the triangle, most likely the right triangle.
Only if it is drawn in 3-dimension. A triangle drawn in 2-dimension does NOT satisfy the criteria. However, a triangle drawen across the surface of a sphere, such as the Earth, does satisfy the criteria.

Measurements of a trigon (or triangle).
By measuring it or using trigonometry.
Trigonometry is specificly the study of a right triangle. For example, what is the cosine? Geometry is the study on shapes.
