What is the angle of elevation?

The angle of elevation is the angle between a horizontal line and the line of sight to a point above that line. It’s measured upward from the horizontal toward the object you’re looking at, which is why this choice matches the standard definition. The other descriptions don’t fit: using a vertical reference would define a different angle, looking down from the horizontal describes the angle of depression, and an angle formed by two lines is just any angle between lines, not specifically the elevation from the horizontal. In practical terms, the angle of elevation helps relate height and distance in problems using tangent, sin, or cos.
