Learn and know how to say **trigonometry definition** in mathematics. Very important chapter in math which has more applications in real life.

Meaning of **trigonometry** is “tri’ means three; “gono” means angle and “metry’ means measurement. So we can say trigonometry means three angle measurements. Where we can observe three angles? We observe in triangles so **trigonometry** deals with triangles. Now we will learn the **definition of trigonometry**.
