subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
Sine and cosine.
The word, trigonometry" is derived from trigon = triangle + metry = measurement. It is based on the study of angles of a triangle and their properties. Although trigonometric ratios are often introduced to students in the context of triangles, their properties for all angles.For example, trigonometric functions are well defined for angles with negative values as well as for more than 180 degrees even though no triangle can possibly have angles with such measures.
Six.
The sum of the angles is 180 degrees. So if the ratios are a, b and c then the angles are180*a/(a+b+c), 180*b/(a+b+c) and 180*c/(a+b+c) degrees.
Right triangle ratios serve as the foundation for defining trigonometric functions such as sine, cosine, and tangent, which relate the angles of a triangle to the lengths of its sides. The unit circle, a circle with a radius of one centered at the origin of a coordinate plane, extends these concepts by allowing trigonometric functions to be defined for all angles, not just those in right triangles. In the unit circle, the x-coordinate corresponds to the cosine of the angle, while the y-coordinate corresponds to the sine, thus linking the geometric representation of angles to their trigonometric values. This connection facilitates the understanding of periodic properties and the behavior of trigonometric functions across all quadrants.
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
Complements are defined for angles, not trigonometric ratios of angles.
Yes, since it has vertices it has angles and since it has angles it has trigonometric ratios
Sine and cosine.
When using inverse trigonometric functions to relate values to angles larger than 90 degrees, we typically use reference angles. Reference angles are acute angles formed between the terminal side of the angle in question and the x-axis. By using reference angles, we can determine the appropriate quadrant and sign for the angle, allowing us to accurately relate the values returned by inverse trigonometric functions to angles greater than 90 degrees.

They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.
Because a right angle will always measure 90 degrees no matter what the dimensions of the triangle are.
There are two main uses. One is, in a complicated shape, to find the measure of an unknown angle using known values of other angles. The other is that trigonometric ratios are related to their supplement angles. Also, the sine of an angle is related to the cosine of of its complement.
They are different trigonometric ratios!
