Using the proportion of parallel lines to determine the missing length of a triangle

👉 Learn how to solve for the unknown in a triangle divided internally such that the division is parallel to one of the sides of the triangle. The triangle proportionality theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally. Thus, with the aid of the triangle proportionality theorem, we can solve for the unknown in a triangle divided proportionally.
