__Math Tutoring on Solving Triangles using the Laws of Cosines__

A triangle that is not a **Right Triangle** is called an **Oblique Triangle**. The **Law of Cosines** will allow us to solve **Oblique Triangles**.

Requirements for solving Oblique Triangles using the **Law of Cosines **in math tutoring:

· **SAS**: Two sides and an included angle are known.

· **SSS**: Three sides are known.

** The Law of Cosines**:

The **Law of Cosines** is a relationship among the angles and sides of a triangle. For any triangle **ABC**, with sides **a**, **b** & **c**

For **Right Triangle**, the **Laws of Cosines** becomes **Pythagorean Theorem.**

Some real life applications of **Law of Cosines** are:

· Determining the width of a lake.

· Determining the distance of plane travels.

· Determining the diagonal of a parallelogram.
