Angle of Elevation and Depression Lesson 7.5
eye - level
The angle between the original line of sight (eye-level) and the new line of sight is known as the angle of elevation because I have to lift up or elevate my eye in order to see the object.
eye - level
The angle between the original line of sight (eye-level) and the new line of sight is known as the angle of depression because I have to look down in order to see the object.
eye - level
The angles are equal – they are alternate angles
