Angle of elevation and depression
Topic Notes
When you look at an object above you, the angle between the horizontal and your line of sight to the object is called the angle of elevation.
When you look at an object below you, the angle between the horizontal and your line of sight to the object is called the angle of depression.
Basic Concepts
- Use sine ratio to calculate angles and sides (Sin = )
- Use cosine ratio to calculate angles and sides (Cos = )
- Use tangent ratio to calculate angles and sides (Tan = )
