What is the triangle proportionality theorem

The video tutorial explains the triangle proportionality theorem, which states that if a line is parallel to one side of a triangle, it creates proportional segments on the other two sides. The instructor guides students through understanding parallel lines in triangles, forming proportions, and using these proportions to solve for variables. The lesson emphasizes recognizing these geometric properties to simplify problem-solving in math.
