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