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.
Calculate the slope of the given line. Any line parallel to it will have the same slope.
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.
No, it cannot.
zero

The Playfair Axiom (or "Parallel Postulate")
Euclid's parallel postulate.
Calculate the slope of the given line. Any line parallel to it will have the same slope.
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.
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.
You construct a line perpendicular to the original and then a line perpendicular to this second line.
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
No, it cannot.
Parallel straight line equations have the same slope but with different y intercepts
