Understanding Key Terms in Trigonometry Applications
1. Angle of Elevation
The angle formed when an observer looks upward at an object. For example, when you look at the top of a building from the ground.
2. Angle of Depression
The angle formed when an observer looks downward at an object, such as viewing something from the top of a tower.
3. Line of Sight
An imaginary straight line from the observer’s eye to the object being viewed.
4. Horizontal Line
A straight line parallel to the ground level, used as a reference in trigonometric problems.
Mastering these definitions is essential for solving questions accurately.
