The answer depends on the method used for constructing the second line. But since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.
One way is to draw a straight line from the constructed line to the given line. If the lines are parallel, than the acute angle at the given and constructed line will be the same as will be the obtuse angles at the given and constructed line.
Calculate the slope of the given line. Any line parallel to it will have the same slope.
True. In Euclidean geometry, if there is a line and a point not on that line, there exists exactly one line that can be drawn through the point that is parallel to the given line. This is known as the Parallel Postulate, which states that for a given line and a point not on it, there is one and only one line parallel to the given line that passes through the point.
zero
bcause you have to make it parallell or it's not a segment.

Show that corresponding angles are congruent?
If the lines have the same slope but with different y intercepts then they are parallel
The Playfair Axiom (or "Parallel Postulate")
By using a protractor which will show that corresponding angles are equal and alternate angles are equal .
Euclid's parallel postulate.

Another name for the Playfair Axiom is the Euclid's Parallel Postulate. It states that given a line and a point not on that line, there is exactly one line parallel to the given line passing through the given point.
Assume there are no lines through a given point that is parallel to a given line or assume that there are many lines through a given point that are parallel to a given line. There exist a line l and a point P not on l such that either there is no line m parallel to l through P or there are two distinct lines m and n parallel to l through P.
Playfair Axiom
[A Parallel line is a straight line, opposite to another, that do not intersect or meet.] Ie. Line 1 is Parallel to Line 2. ------------------------------------------------- <Line 1 ------------------------------------------------- <Line 2
