Geometry -Solve the missing length using the triangle bisector theorem

The video tutorial explains the concept of an angle bisector in a triangle, which divides the triangle into two similar triangles. It demonstrates how to set up proportions using the sides of the triangle and solve for unknown values using cross multiplication. The tutorial concludes with a practical example to reinforce the learning.
