HEIGHTS AND DISTANCES
In this chapter we learn how to use the trigonometric ratios to calculate heights of objects and distances between objects by measuring angles rather than sides.
ANGLE OF ELEVATION
Angle of elevation of a point P as observed from a point O (Refer figure) is the Angle POR where R is the foot of the […]

The branch of mathematics dealing with the relationships between the angles and the sides of triangles, and the calculations based on them. It originated as the study of certain mathematical relations in a triangle containing a right angle (90°). Literally, it means triangle measurement, though its applications extend far beyond geometry. It emerged as a […]
