What is the converse of the theorem statement: If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.
If two sides of a triangle are divided in the same proportion, then the line connecting the dividing points on the sides is parallel to the third side of the triangle.
But how do I write it? Example: is it
A. In triangle QRS, ig RT/TQ=RU/US, then side TU is parallel to side QS.
B. In triangle ABC, if CD=DA and CE=EB,then side DE is parallel to side AB and DE=1/2AB
c. In triangle QRS, if side TU is parallel to side QS, then RT/TQ=RU/US.
