What are the names of Non-Euclidean Geometries?
Answer The two commonly mentioned non-Euclidean geometries are hyperbolic geometry and elliptic geometry. If one takes "non-Euclidean geometry" to mean a geometry satisfying all of Euclid's postulates but the parallel postulate, these are the two possible geometries.
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.
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 postulate is not of euclidean geometry?
Euclidean Geometry is based on the premise that through any point there is only one line that can be drawn parallel to another line. It is based on the geometry of the Plane. There are basically two answers to your question: (i) Through any point there are NO lines that can be drawn parallel to a given line (e.g. the geometry on the Earth's surface, where a line is defined as a great circle. (Elliptic Geometry) (ii) Through any point, there is an INFINITE number of lines that can be drawn parallel of a given line. (I think this is referred to as Riemannian Geometry, but someone else needs to advise us on this) Both of these are fascinating topics to study.
Are parallel lines coplanar?
In Euclidean geometry, parallel line are alwayscoplanar.
What are the two kinds of geometry?
euclidean Geometry where the parallel line postulate exists. and the is also eliptic geometry where the parallel line postulate does not exist.
Are the rules of parallel and perpendicular lines different in spherical geometry than in Euclidean geometry?
yes

Why don't parallel lines exist in elliptical geometry?
Elliptical geometry is a non-Euclidean geometry. The parallel postulate of Euclidean geometry was replaced by the statement that through any point in the plane, there exist no lines parallel to a given line. A consistent geometry - of a space with positive curvature - was developed on that basis.It is, therefore, by definition that parallel lines do not exist in elliptical geometry.
What Compare and contrast the major characteristics of euclidean and non euclidean geometry?
Euclidean geometry is based on the principles outlined by Euclid, emphasizing flat spaces and relying on postulates such as the parallel postulate, which states that through a point not on a given line, exactly one parallel line can be drawn. In contrast, non-Euclidean geometry arises when this parallel postulate is altered, leading to geometries such as hyperbolic and elliptic geometry, where multiple parallels can exist or none at all. While Euclidean geometry deals with shapes and figures in two-dimensional flat planes, non-Euclidean geometry explores curved surfaces and spaces, resulting in different properties and relationships among points, lines, and angles. Overall, the key distinction lies in the treatment of parallel lines and the nature of space itself.
What is Euclidean geometry mean in math?
Euclidean geometry is the traditional geometry: it is the geometry of a plane surface, as developed by Euclid. Among other things, it is based on Euclid's parallel postulate which said (in effect) that given a line and a point outside that line there could only be one line through that point that was parallel to the given line. It has since been discovered that both alternatives to that postulate - that there are many such lines possible and that there are none - give rise to consistent geometries. These are non-Euclidean geometries.
What was A postulate that was developed and accepted by greek mathematicians?
One postulate developed and accepted by Greek mathematicians was the Parallel Postulate, which stated that given a line and a point not on that line, there is exactly one line through the point that is parallel to the given line. This postulate was crucial in the development of Euclidean geometry. However, it was later discovered that this postulate is not actually necessary for generating consistent geometries, leading to the development of non-Euclidean geometries.
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.
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 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.
How many right angles dose a kite have?
If you mean a toy kite, it could have any number. If you mean the geometrical figure, in Euclidean geometry it could have zero, one, or two. It can't have four because then it would be a square rather than a kite, and it can't have three because that can be proven to be impossible in Euclidean geometry(if it has three, it must of necessity have four thanks to the parallel postulate).In non-Euclidean geometry (which denies the parallel postulate), a kite with three right angles is possible and is called a Lambert quadrilateral.
