Answer variants:
If a ray stands on a line, then the sum of two adjacent angles so formed is \(180^\circ\)
When two lines intersect, then the vertically opposite angles are not equal
If a transversal intersects two lines such that a pair of interior angles on the same side of the transversal is supplementary, then the two lines are not parallel.
The sum of the angles of a triangle is \(180^\circ\).
If a transversal intersects two lines such that a pair of corresponding angles are equal, then the two lines are parallel to each other.
