Height and distance  handwritten notes 

The topic heights and distance is one of the applications of Trigonometry, which is extensively used in real-life. The words height and distance are frequently used in the trigonometry while dealing with its applications. In the height and distances application of trigonometry, the following concepts are included:

• Measuring the heights of towers or big mountains
• Determining the distance of the shore from the sea
• Finding the distance between two celestial bodies

It should be noted that finding the height of bodies and distances between two objects is one of the most important applications of trigonometry.

What are Heights and Distances?

The most significant definitions that are used when dealing with heights and distances are given as:

• Definition 1: – Line of Sight –  The line which is drawn from the eyes of the observer to the point being viewed on the object is known as the line of sight.
• Definition 2:  – Angle of Elevation – The angle of elevation of the point on the object (above horizontal level) viewed by the observer is the angle which is formed by the line of sight with the horizontal level.
• Definition 3: – Angle of Depression – The angle of depression of the point on the object (below horizontal level) viewed by the observer is the angle which is formed by the line of sight with the horizontal level.
