Angle of Elevation

Angle of Elevation Line of sight.jpg

 

Suppose the girl wants to see the boy at the top of the Eiffel tower.

Her eyes will see towards to the top.

 

The line from the girl’s eyes to the top of Eiffel Tower is Line of Sight

 

To measure angle,

we draw a horizontal from the girl’s eyes

Horizontal is a line which is parallel to the ground

Angle of Elevation and Angle of Depression - Part 2

Angle between line of sight and horizontal when object is above eye level is angle of elevation

 

Note: In Angle of elevation, person is looking above.

 

Angle of Depression

Angle of Elevation and Angle of Depression - Part 3

Now suppose there is a boy at the top of tower.

He is watching a girl at the bottom

His eyes will see towards to the bottom.

 

The line from the boy’s eyes to the girl is Line of Sight

 

To measure angle,

we draw a horizontal from the boy’s eyes

Horizontal is a line which is parallel to the ground

Angle of Elevation and Angle of Depression - Part 4

Angle between line of sight and horizontal when object is below eye level is angle of depression

 

Note: In Angle of depression, person is looking below.
