Trigonometric Ratios

The ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse is called cosine.
The ratio of the length of the side opposite an acute angle to the length of the hypotenuse is called sine.
The ratio of the length of the side opposite an angle to the length of the side adjacent to the angle is called tangent.
The trigonometric ratio for a 30-degree angle in a right triangle is 1/2.
The trigonometric ratio for a 45-degree angle in a right triangle is 1/√2 or √2/2.
The trigonometric ratio for a 60-degree angle in a right triangle is √3/2.
There is no trigonometric ratio for a 90-degree angle in a right triangle, as the ratio is undefined.
The trigonometric ratio for a 0-degree angle in a right triangle is 0.
