Construction of Angles and Tools

This video tutorial demonstrates how to construct a 22.5-degree angle using basic geometric tools. It begins with drawing a horizontal line and progresses through constructing 60, 120, 90, and 45-degree angles. The final step involves dividing the 45-degree angle to achieve the desired 22.5-degree angle. The tutorial concludes with a summary and encourages viewers to engage with the content.
