When you have two sides of a triangle and the angle between them, otherwise known as SAS (side-angle-side), you can use the law of cosines to solve for the other three parts. Consider the triangle ABC where a is 15, c is 20, and angle B is 124 degrees. The following figure shows what this … Students will practice applying the law of cosines to calculate the side length of a triangle and to calculate the measure of an angle. Students will also extend their thinking by applying the law of cosines to word problems and challenge questions.

In such cases, the law of cosines may be applied. To prove the theorem, we place triangle ∆ABC in a coordinate plane with vertices labeled counterclockwise and so that one side lies on the positive x axis and one vertex is at O. Suppose that A is at ( 0 , 0 ) . Then B = ( c , 0 ) and C = ( b cosα, b sinα).

8-6: Law of Cosines The Law of Cosines Another relationship between the sides and angles of any triangle is called the Law of Cosines. You can use the Law of Cosines if you know three sides of a triangle or if you know two sides and the included angle of a triangle. Law of Cosines Remember that the Law of Cosines works for any triangle, not just right triangles. In the last lesson we used the Law of Cosines to find the length of the third side of a triangle when you know the length of two sides and the angle in between. This law can also be used to find the measure of an angle when the three sides of a triangle are given.

Two great law of sines problems. These two law of sines problems below will show you how to use the law of sines to solve some real life problems. Problem #1 Two fire-lookout stations are 15 miles apart, with station A directly east of station B. Both stations spot a fire. The Law of Cosines is used when we have all three sides and only one angle. This rule is similar to the Pythagorean theorem & you can use it to solve triangles that are not right-angled. Use right triangle trigonometry and the Pythagorean Theorem to develop the Law of Cosines.
