Law of Sines and Cosines

The video tutorial introduces the use of theodolites for triangulation, explaining how precise angular measurements help determine positions and directions. It covers the naming conventions for triangles, emphasizing the importance of using uppercase letters for angles and lowercase for sides. The tutorial explains the laws of sines and cosines, providing real-life applications such as calculating the height of a cliff and determining the fencing needed for a triangular field. The video highlights the practical use of trigonometry in solving real-world problems.
