The angle of elevation: For objects above horizontal level, the angle of elevation is important. It's the angle that the line of sight makes with the horizontal level.
The angle of depression: For objects below horizontal level, the angle of depression is important. It's the angle that the line of sight makes with the horizontal level.
Height and Distance Calculations: We can use trigonometric ratios to calculate heights and distances.
Step 1: Make a line diagram that corresponds to the issue.
Step 2: Make a list of all known heights, distances, and angles, and use variables to represent unknown lengths.
Step 3: Subtract the unknown lengths from the known lengths using the values of various trigonometric ratios of the angles.
Using trigonometry to calculate the distances between celestial bodies: The parallax method can be used to measure large distances. When an object is viewed from two different perspectives, the parallax angle is half the angle between two lines of sight. Large distances can be measured using the parallax angle and the distance between the two positions.

Frequently Asked Questions
Que1. What is the definition of trigonometry class 10 introduction?
Answer1. The science of relationships between the sides and angles of a right-angled triangle is known as trigonometry. Trigonometry Ratios (also known as trigonometric ratios) are a type of ratio which shows the ratios of the sides of a right triangle. Consider the triangle ABC, which has a right angle at B. These proportions are always expressed in terms of acute angle 'A' or acute angle 'C.'
