Some Applications of Trigonometry ght i s f o tion a Line v e l of e e l g n A Horizontal level Angle of d epression Line of si ght Theodolite is e an instrument to find out horizontal or vertical angles and thus enable us to find heights and distances of objects in our daily life. Line of sight • Line drawn from the eye of an observer to the point in object viewed. Angle of elevation Angle of depression • Angle between line of sight and horizontal level. • Above horizontal • Angle formed between line of sight and horizontal level. • Below horizontal MIND MAP. . .
