Determine the quadrant to sketch your angle based on the constraint

The video tutorial explains how to determine the placement of angles in different quadrants based on constraints. It emphasizes constructing triangles with correct angles, ensuring they are perpendicular to the X-axis. The tutorial also covers cosine values, the Pythagorean theorem, and the importance of triangle orientation, highlighting how the direction affects the sign of the sides.
