Hyperbolic geometry is a beautiful example of non-Euclidean geometry. One feature of Euclidean geometry is the parallel postulate. This says that give a line and a point not on that line, there is exactly one line going through the point which is parallel to the line. (That is to say, that does NOT intersect the line) This does not hold in the hyperbolic plane where we can have many lines through a point parallel to a line. But then we must wonder, what do lines look like in the hyperbolic plane? Lines in the hyperbolic plane will either appear as lines perpendicular to the edge of the half-plane or as circles whose centers lie on the edge of the half-plane
The transversal is the line that cuts the parallel line.
Alternate angles are where two parallel lines have a line through them.
A parallel line is two lines along the same path in the same direction. Also parallel lines always have to be straight Some examples of parallel lines are below. \ | | / / = ll
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.
zero
A transversal line cutting through parallel lines creates various angles
parallel lines are those line which does not have any intersecting point.
infinitely many
Two parallel lines, a plane and a line in a plane parallel to it.
Non-parallel lines intersect at some point, parallel lines don't.
The line that cuts a parallel line is called a TRANSVERSAL. When you have parallel lines and you want to show like corresponding, vertical, ect.... then the line that cut through the parallel lines is a TRANSVERSAL
The two lines are identical.
Any line that is not parallel to the given lines. The transversal that contains the shortest distance between the two parallel lines, is perpendicular to them.

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!
