In reference [1], and pretty much in standard trigonometry and precalculus texts,the Law of Cosines is employed in solving a SAS triangle. In this work we use an alternative approach by using the Law of this http URL Section 2, we list some basic trigonometric identities and in Section 3...
The law of sines is useful in solving a triangle since it makes use of the relationships of the sides and angles of a triangle. Learn how to solve...
Solving a triangle means determining the unknown parts of the triangle which are the unlabeled sides and angles. There are different approaches to finding the unknowns like using the sum of the interior angles, the law of sines, the law of cosines and even the Pythagorean t...
Find Sides using Perimeter Given the perimeter of an equilateral triangle, the side lengths can be found using this formula: a = p / 3 Because each side is equal in length, the length of side a is equal to the perimeter p divided by three. How to Find the Height of an Equilatera...
