## Understanding Right Triangles and Trigonometry

In Unit 7 of your math curriculum, you will dive into the world of right triangles and trigonometry. This unit is important as it provides a foundational understanding of the relationships between the angles and sides of a right triangle, as well as the application of trigonometric functions such as sine, cosine, and tangent.

Right triangles are a fundamental concept in mathematics and have practical applications in various fields such as engineering, architecture, and physics. Trigonometry, on the other hand, deals with the study of the relationships between the angles and sides of triangles. It is an essential tool for solving real-world problems involving measurements and angles.
