Non-Euclidean and Euclidean geometries differ in their treatment of parallel lines. In Euclidean geometry, parallel lines never intersect and the sum of angles in a triangle is always 180 degrees. In non-Euclidean geometries, such as hyperbolic and elliptic geometries, parallel lines can intersect and the sum of angles in a triangle can be greater than or less than 180 degrees. This results in different properties and theorems in non-Euclidean geometries compared to Euclidean geometry. **

Euclidean or Euclidean space refers to a geometric space that follows the principles and axioms laid out by the ancient Greek mathematician Euclid. In Euclidean space, the basic concepts of points, lines, and planes are defined, and the properties of these elements are described using Euclidean geometry. This space is characterized by the parallel postulate, which states that given a line and a point not on the line, there is exactly one line parallel to the given line through the point. Euclidean space is the foundation of classical geometry and is used extensively in mathematics and physics. **

Euclidean space is a mathematical concept that refers to a geometric space in which the fundamental concept of distance between points is defined. It is named after the ancient Greek mathematician Euclid, who laid the foundations for the study of geometry. In Euclidean space, the distance between two points is calculated using the Pythagorean theorem, and the space is characterized by its flat, straight-line geometry. It is the basis for much of classical geometry and serves as a fundamental framework for understanding spatial relationships in mathematics and physics. **

The extended Euclidean algorithm is an extension of the Euclidean algorithm, which is used to find the greatest common divisor of two numbers. In addition to finding the greatest common divisor, the extended Euclidean algorithm also finds the coefficients of Bézout's identity, which are used to express the greatest common divisor as a linear combination of the two numbers. This algorithm is particularly useful in number theory and cryptography, as it can be used to find modular inverses and solve linear Diophantine equations. **

The weighted Euclidean norm is a way to measure the distance between two points in a multi-dimensional space, where each dimension is given a different weight. It is calculated by taking the square root of the sum of the squared differences between the coordinates of the two points, with each difference being multiplied by the corresponding weight. This allows for certain dimensions to have a greater impact on the overall distance calculation, reflecting their relative importance in the context of the problem being analyzed. The weighted Euclidean norm is a useful tool in various fields such as statistics, machine learning, and physics, where different dimensions may have different levels of significance. **

The Euclidean algorithm for 2 is a method for finding the greatest common divisor (GCD) of two numbers. It involves dividing the larger number by the smaller number and then using the remainder as the new smaller number in the next iteration. This process is repeated until the remainder is 0, at which point the GCD is the last non-zero remainder. For example, to find the GCD of 24 and 18 using the Euclidean algorithm for 2, we would divide 24 by 18 to get a remainder of 6, then divide 18 by 6 to get a remainder of 0, so the GCD is 6. **

The Euclidean algorithm can be extended to work with three numbers by repeatedly applying the algorithm to pairs of the three numbers. First, we find the greatest common divisor (GCD) of the first two numbers using the Euclidean algorithm. Then, we find the GCD of the result with the third number. This process is repeated until we have found the GCD of all three numbers. The final result will be the greatest common divisor of the three numbers. **
