Finding Unknown Angles in Geometry

The video tutorial guides students through the process of identifying and calculating unknown angles in a geometric figure. It begins with an introduction to the concept of angles and proceeds to measure specific angles, HGK and FGK, using given values. The tutorial then focuses on finding the unknown angle FGH by applying the part-part-whole relationship, subtracting the known angle from the total. The video concludes with encouragement for students to practice finding unknown angles independently.
