Azimuth and Bearing Calculations

The video tutorial explains how to compute azimuth and bearing angles in polygons, focusing on a pentagon. It covers the importance of verifying the sum of interior angles, calculating azimuth angles in both clockwise and counter clockwise directions, and understanding the concept of alternate angles in bearing computations. The tutorial provides step-by-step instructions for calculating azimuths and bearings, emphasizing the use of reverse angles and Z angles.

What is the sum of the interior angles of a pentagon?

• 720 degrees
