[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
Oh, dude, finding the slope of a line parallel to another line is like finding a matching sock in a pile of laundry. The slope of a line parallel to y = 4x - 2 is just the same as the slope of the original line, which is 4. So, like, the slope of the parallel line is also 4. Easy peasy lemon squeezy.
y = 3x+5 is parallel to y = 3x+7
The locus of points at a given distance to a line would be a line parallel to the first line. Assuming that both lines are straight.
Yes, a transversal line always intersects two parallel lines.
True
Two lines are not parallel if they have exactly one point in common; otherwise they are parallel. So this means a line is parallel to itself!
The Playfair Axiom (or "Parallel Postulate")
Yes. That's always possible, but there's only one of them.
Neither: because one line, by itself, can be neither parallel or perpendicular. These characteristics are relevant only in the context of another line (or lines). The given line is parallel to some lines and perpendicular to others.
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.
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.
