8.4 Angles of Elevation & Depression 

An angle of elevation is the angle formed by the horizontal line and a line of sight to a point above the line.

An angle of depression is the angle formed by the horizontal line and a line of sight to a point below the line.

*What do we know about <1 and <2?
