Three straight lines have exactly two points of intersection. Complete the sentence below. Two of the lines must be **parallel Parallel lines never intersect those two lines intersect third line at two points **
When three straight lines intersect to form exactly two intersection points, it indicates that two of the lines must be parallel. One line intersects the other two lines at different points, while the parallel lines do not intersect each other. This relationship is derived from the principles of Euclidean geometry.
