Chapter 9 : Solution of Triangles
What will you learn in this chapter
We will start by understanding the Sine Rule, which helps us find the relationship between the ratio of the lengths of the sides of a triangle and the sine of the opposite angles.
Next, we will learn about the Cosine Rule, which allows us to find the length of a side or the measure of an angle in a triangle.
We will also explore how to find the area of a triangle using different formulas.
Lastly, we will apply the Sine Rule, Cosine Rule, and the area of a triangle to solve various triangle problems.
By the end of this chapter, we will be able to solve triangles using these rules and formulas.
