The Euclidean Parallel Axiom is as stated below:
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.
My source is linked below.
The Euclidean Parallel Axiom states that through a point not on a given line, there exists exactly one line parallel to the given line. This axiom is one of the five postulates in Euclidean geometry that forms the foundation for the study of parallel lines and geometry.

How many parallel lines in a cylinder 2?
A cylinder includes an infinite number of parallel lines. Every line in the curved surface is parallel to every other one and perpendicular to the two ends. . "A cylinder 2" is meaningless. You would have to look at the homework you're trying to get the answer for to see what cylinder 2 means.
Compare parallel and cooperative play?
In parallel play, children play alongside each other without interacting or sharing toys, while in cooperative play, children engage in a shared activity, collaborate, and work together towards a common goal. Parallel play is common in younger children as they explore their surroundings, while cooperative play becomes more prevalent as children grow and develop social skills. Both types of play are important for children's social development.
A quadrilateral with exactly 1 pair of parrell sides and exactly 1 pair of congruent sides?
This quadrilateral is a trapezoid. In a trapezoid, one pair of opposite sides is parallel, and one pair of opposite sides is congruent. The other two sides are not parallel or congruent.
What is the vertical cross section of a cylinder?
The vertical cross section of a cylinder is a rectangle. It is created by slicing the cylinder along a plane parallel to its base. The resulting shape will have the same height as the cylinder but a width equal to the diameter of the base.
What are the basic constructions required by Euclid's postulates?
The basic constructions required by Euclid's postulates include drawing a straight line between two points, extending a line indefinitely in a straight line, drawing a circle with a given center and radius, constructing a perpendicular bisector of a line segment, and constructing an angle bisector. These constructions are foundational in Euclidean geometry and form the basis for further geometric reasoning.
Why is the parallel axiom in Euclid's geometry false in non-Euclidian geometry?
Euclid's parallel axiom is false in non-Euclidean geometry because non-Euclidean geometry occurs within a different theory of space. There may be one absolute occurrence in non-Euclidean space where Euclid's parallel axiom is valid. Possibly as some form of infinity.
Which euclidean axiom has been considered controversial?
the 5th one
What is two point form of a line?
An axiom of Euclidean geometry.
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.
Do parrallel lines meet?
Not in Euclidean Geometry. Euclid's 5th axiom is that parallel lines never meet. However, unlike the first 4 axiom, it is impossible to prove the 5th axiom; depending upon the situation, you can either assume that parallel lines meet or don't; when they do meet, there are some very interesting consequences (for example, the possibility of a hyperbolic space). To my knowledge, if they meet, they are intersecting/perpendicular lines.
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 is the difference between Euclidean Geometry and non-Euclidean Geometry?
In Euclidean geometry parallel lines are always the same distance apart. In non-Euclidean geometry parallel lines are not what we think of a parallel. They curve away from or toward each other. Said another way, in Euclidean geometry parallel lines can never cross. In non-Euclidean geometry they can.
Is it true that the sum of three angles of any triangle is 180 in non euclidean geometry?
No. Non-Euclidean geometries usually start with the axiom that Euclid's parallel postulate is not true. This postulate can be shown to be equivalent to the statement that the internal angles of a traingle sum to 180 degrees. Thus, non-Euclidean geometries are based on the proposition that is equivalent to saying that the angles do not add up to 180 degrees.
Will parallel lines intersect?
In Euclidean space, never. But they can in non-Euclidean geometries.
Are parallel lines coplanar?
In Euclidean geometry, parallel line are alwayscoplanar.
