The side-splitter theorem states that <em>"if a line is parallel to a side of a triangle and the line intersects the other two sides, then this line divides those two sides proportionally".</em>
<em />
Based on this theorem, which an elaborate the following proportion
Therefore, the segment that completes the proportion is GJ, because it must be used according to the theorem.
Side-splittertheorem states that if a line is parallel to one of the sides of a triangle and intersects two other sides, then it divides the two other sides in equal proportion.
As per the given diagram,
We see line is such a line which is parallel to side of .
