Trigonometric Ratios in Right Triangles

How to effectively deal with bots on your site? The best protection against click fraud.

In this video I will explain the trigonometric ratios in the right triangle.

It is also related to mathematics for its trigonometric ratios.

They can only be applied to right triangles since they follow some criteria by which they have to have legs and hypotenuse.

The sine, cosine, and tangent can be used to find the angles and measurements of sides unknown.

  • The hypotenuse, is the side opposite the 90º angle and is the longest side of a right triangle.
  • The Hick opposite, is the side opposite the opposite angle considered.
  • The adjacent leg, is the leg that forms the acute angle considered.

Breast of an angle is the quotient between the length of the opposite leg and the hypotenuse.

Sine = opposite / hypotenuse

The cosine of an angle is the quotient between the length of the contiguous or adjacent leg divided by the hypotenuse.

Cosine = adjacent / hypotenuse

Tangent of an angle is the quotient between the length of the opposite leg divided by that of the adjacent leg.

Tangent = opposite / adjacent
