Elaborate more on your question! Include details that we don't know.
First off, Parallel lines are two lines that lie within the same plane and never intersect, So the undefined terms that are needed to define a parallel line are Lines, planes.
D as you can see on the number line d is 1/3 of the way to -2
Answer:
The reason why linear pairs and vertical angles are used to prove lines are parallel is because they area transversal drawn through the parallel lines will form angles on each of the two parallel lines including;
1) Supplementary linear pairs and
2) Vertical angles
3) Alternate angles
Given that either;
a) The corresponding angles that form the linear pairs are congruent
b) The corresponding vertically opposite angles are congruent
c) The corresponding alternate angles are congruent, we have;
The two lines are said to be parallel.
