Use the converse of the side-splitter theorem to determine if tu || rs. which statement is true? line segment tu is parallel to line segment rs because 32/36 = 40/50 line segment tu is not parallel to line segment rs because 32/36 not equal 40/50. line segment tu is parallel to line segment rs because 32/36 = 40/50. line segment tu is not parallel to line segment rs because 32/36 not equal 40/50 .
