Answer: Sometimes
Step-by-step explanation:
If the line that passes through two sides of a triangle divides the sides is parallel to the third side then by Basic proportionality theorem it divides the sides proportionally.
Otherwise it does not divide the sides proportionally.
Basic Proportionality Theorem tells that if a line is drawn parallel to one side of a triangle intersecting other two sides, then it divides the two sides in the same ratio.
