Trigonometry helps us in finding height of objects and distances between the points without actually measuring them.

 

 

Angle of Evaluation: Let PQ be a tower (pillar/shell/miner/pole) etc...Standing on a level ground and the observer is standing at any point R on the level ground, is viewing at P.

 

 

The angle, which the line RP makes with the horizontal line RQ is called angle of evaluation. So, Angle PQR is angle of evaluation.

Angle of Depression: If observer is at Q and S viewing object R on the ground, the angle between PQ and QR is the angle of depression, so, angle PQR is angle of depression.

 

 

Numerically angle of evaluation is equal to the angle of depression.

The angle of evaluation and the angle of depression both are measured with the horizontal.

Height and Distance Problems are useful for Competatitive Exams.
