Definition of Origin in Math. In mathematics, especially in the field of coordinate geometry; origin is said to be the initial point or the starting point from where we begin our calculations or measurements. On a ruler, the 0 is from where we start our measurements; hence it is said to be the origin of the scale.

Figure 2.1. Points and free vectors. pair (O; (e1; e2; e3)) consisting of an origin O (which is a point) together with a basis of three vectors (e1; e2; e3). For example, the standard frame in R3 has origin O = (0; 0; 0) and the basis of three vectors e1 = (1; 0; 0), e2 = (0; 1; 0), and e3 = (0; 0; 1).
Aug 3, 2023 · Point Symmetry is also called Origin Symmetry , since the ‘Origin’ is the central point about which the shape is symmetrical. Thus, when we rotate a figure about 180° and it regains its originals shape, only then we say that point symmetry exists in the figure. Solved Examples. Does a regular pentagon has point symmetry? Solution:
In mathematics, the origin of a Euclidean space is a special point, usually denoted by the letter O, used as a fixed point of reference for the geometry of the surrounding space. In physical problems, the choice of origin is often arbitrary, meaning any choice of origin will ultimately give the same answer.
