Law cosines calculator

Use our Law of Cosines calculator to find any angle or side of a triangle given other known properties.

One method to find the lengths of the sides and measures of angles in a triangle is through the law of cosines. The law of cosines calculator uses this method to find the desired properties of a triangle quickly and efficiently. The Law of cosines is really a form of the Pythagorean theorem, modified for use of non-right triangles. It describes the association between the lengths of the sides of any triangle. Now we can use the law of cosines for a variety of things involving a triangle. First, you can obtain the length of the third side of a triangle knowing the other two side lengths and the angle between them.

The Law of Cosines Calculator is an online tool for solving triangles using the cosine law. Use our free online calculator to determine the unknown side lengths or angles of a triangle. You must have at least one side and either two other sides or a side and an angle. For scenarios with two known sides and one angle, enter the given side lengths and the known angle in the input fields. To find angles with three available side lengths, input them in the corresponding fields. The calculator will instantly display the missing side lengths or angles using the law of cosines. The Law of Cosines, also known as the Cosine Rule or Cosine Formula, is an important geometry formula that relates the sides and angle of any triangle, be it acute, obtuse, or right-angled. It extends the Pythagorean theorem, a particular case for right triangles. The Law of Cosines is a fundamental equation in geometry that relates the lengths of the sides of a triangle with the cosine of one of its angles.
