Bisecting Angles and Compass Use

In this video, Math-o-Fanatic demonstrates how to bisect an angle using a compass and straightedge. The process involves setting the compass to a comfortable length, striking arcs, and drawing a line through the vertex and intersection of arcs to create an angle bisector. The tutorial emphasizes the simplicity and speed of the method, encouraging viewers to practice and ask questions if needed.
