Lesson Summary:
Students need to learn the distance and height determination techniques of a remote object. It is important to increase the use of trigonometric ratios in the present age. The height of mountains, mountains, towers, plant height, and river width are not easily measured, In that case can be determined with the help of trigonometry.
Lesson Objective:
At the end of this lesson, students will be able to solve geometrical, arithmetic, vertical, progressive angle and degradation angle and solve arithmetic problems with distance and height
Type of resource: Trigonometry
Level: secondary
Subject: mathematics
