To calculate the other angles, we need the sine, cosine and tangent. In fact, the sine, cosine and tangent of an acute angle can be defined by the ratio between sides in a right triangle. Just like every other triangle, a right triangle has three sides. One of them is the hypothenus...
Calculating the sides of a triangle helps you to determine the perimeter of a triangle even if you only have the measure of two of the angles and one of the sides. To find the sides of the triangle, you need to use the Law of Sines. A scientific calculator with trigonometric functions ...
A right triangle or right-angled triangle, or more formally an orthogonal triangle, is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse. If...
meaning that you can always find the value of one angle in a triangle if you know the other two. This task is made easier for special triangles such as the equilateral, which has three equal sides and angles and the isosceles, which...
TheLaw of Sinesdescribes the relationship between the sides and angles of oblique (scalene) triangles. sin(α)/a=sin(β)/b=sin(γ)/c You can use the Law of Sines to solve for the angle or side of any triangle. All you need is one angle and the side opposite of that angle. ...

The sine of an angle is given by the quotient between the opposite side and the hypotenuse of a right triangle. This quotient, as well as other types of quotients, are known as trigonometric ratios. These trigonometric ratios are basic tools used in trigonometry to study right triangl...
