Yes.
According to Euclid's 5th postulate, when n line falls on l and m and if
, producing line l and m further will meet in the side of ∠1 and ∠2 which is less than
If
The lines l and m neither meet at the side of ∠1 and ∠2 nor at the side of ∠3 and ∠4. This means that the lines l and m will never intersect each other. Therefore, it can be said that the lines are parallel.

If there is a line and a point not on the line then there is exactly lines trough the point parallel to the given line?
This is Euclid's fifth postulate, also known as the Parallel Postulate. It is quite possible to construct consistent systems of geometry where this postulate is negated - either many parallel lines or none.
What are different ideas about geometry?
The main different ideas are based on Euclid's fifth postulates, more commonly known as the parallel postulate. Unlike his other postulates which are simple and self-evident, the parallel postulate is not.Along with the other postulates, the Fifth postulate is equivalent to the assertion that given a straight line and a point not on that line, there is exactly one line which goes through the given point and is parallel to the given line. A consistent geometry can be developed from these axioms.However, it is also possible to develop wholly consistent geometries with either of the two alternatives to the parallel postulate. One is that no such parallel lines exist and this gives rise to affine or projective geometries. The other is that there are more than one parallel lines and this gives rise to elliptic geometry.
What is the major premise that separates Euclidean geometry from other non-Euclidean geometries?
It is Euclid's fifth postulate which is better known as the parallel postulate. It appears in very many equivalent forms but basically it states that: given a line and a point that is not on that line, there is at most one line which passes through that point and which is parallel to the original line.
What are the postulate involving points lines and plane?
Euclid's first four postulates are:A straight line segment can be drawn joining any two points.Any straight line segment can be extended indefinitely in a straight line.Given any straight line segment, a circle can be drawn havibg the segment as radius and one endpoint as centre.All right angles are congruent. He also had the fifth postulate, equivalent to the parallel postulate. There are various equivalent versions.If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side, if extended far enough.The fifth postulate cannot be proven and, in fact, it is now known that it cannot be proven and that there are many internally-consistent geometries in which the negations of this postulate are true.
Which postulates led to the discovery of non-Euclidean geometry?
Adding to what Anand Mehta said, the negation of that statement has two interpretations. (i) there are zero lines through that point that are parallel to the given line (this is called Elliptic or Reimannian Geometry) (ii) there is an infinite number of lines that pass through the point and parallel to a given line (this is called Hyperbolic or Lobachevskian Geometry) I might add that the study of non-Euclidean Geometries are absolutely fascinating.

Through a point not on the line exactly one line can be drawn parallel to the?
... given line. This is one version of Euclid's fifth postulate, also known as the Parallel Postulate. It is quite possible to construct consistent systems of geometry where this postulate is negated - either many parallel lines or none.
Are two lines that are parallel to the same line parallel to each other?
Yes they are. It is delineated in something called the parallel postulate, and the axiom is also called Euclid's fifth postulate. This is boilerplate Euclidean geometry, and a link can be found below if you'd like to review the particulars.

What are the postulates that non-Euclidean geometry is based on?
Non-Euclidean geometries are based on the negation of his parallel postulate (his fifth postulate). The other Euclidean postulates remain.A rephrasing of Euclid's parallel postulate is as follows:For any given line â„“ and a point A, which is not on â„“, there is exactly one line through A that does not intersect â„“. (The other postulates confirm the existence of â„“ and A.)One set of alternative geometries (projective geometry, for example) is based on the postulate that there are no such lines. Another set of is based on the postulate of an infinite number of lines.
Why hilbert axiom of parallelism assert the existence of only at most one parallel line'?
There is a subtle distinction between Euclidean, Hilbert and Non-Euclidean planes. Euclidean planes are those that satisfy the 5 axioms, while Non-Euclidean planes do not satisfy the fifth postulate. This means that in Non-Euclidean planes, given a line and a point not on that line, then there are two (or more) lines that contain that point and are parallel to the original line. There are geometries where there must be exactly one line through that point and parallel to the original line and then there are also geometries where no such line contains that point and is parallel to the original line.Basically, the fifth postulate can be satisfied by multiple geometries.
An axiom or a is an accepted statement of fact?
A postulate is assumed to be a fact and used to derive conclusions. However, there is no assurance that the postulate is itself true and so all the derived conclusions may depend on a proposition that is not necessarily true. Euclid's fifth, or parallel) postulate in geometry is a notable example.
Does fifth postulate of Euclid imply the existence of parallel lines?
Yes.According to Euclid's 5th postulate, when n line falls on l and m and if, producing line l and m further will meet in the side of ∠1 and ∠2 which is less thanIfThe lines l and m neither meet at the side of ∠1 and ∠2 nor at the side of ∠3 and ∠4. This means that the lines l and m will never intersect each other. Therefore, it can be said that the lines are parallel.

What is the fifth postulate of Euclid's?
The parallel postulate: "That, if a straight line falling on two straight lines make the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which are the angles less than the two right angles."
State the Playfair's axiom using the Euclid's fifth postulate?
Exactly one line can be drawn through any point not on a given line parallel to the given line in a plane Euclids 5th states If a line segment intersects two straight lines forming two interior angles on the same side that sum to less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles.
How can we rewrite Euclid's fifth postulate?
Euclid's fifth postulate: If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.It can be rewritten: If two lines are drawn which intersect a third at angles of 90 degrees, the two lines are parallel and will not intersect each other.It has also been rewritten as Playfair's axiom:In a plane, given a line and a point not on it, at most one line parallel to the given line can be drawn through the point.
