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.

A series of worksheets and lesson that will have students explore figures and identify point symmetry. Print our free worksheets and lessons now.
The starting point. On a number line it is 0. On a two-dimensional graph it is where the X axis and Y axis cross, such as on the graph here: Sometimes written as the letter O. In three dimensions it is the point (0, 0, 0) where the x, y and z axis cross: Cartesian Coordinates. Illustrated definition of Origin: The starting point.

Nov 21, 2023 · In mathematics, an origin is a starting point on a grid that's the point (0,0), where the x-axis and y-axis intercept. The origin is used to determine the coordinates for every other point on the ...

Point symmetry exists when a figure is built around a single point called the center of the figure. Every point in the figure has another point found directly opposite it on the other side of the center. Simple tests to determine a figure has point symmetry it upside-down and see if it looks the same. A figure that has point symmetry is ...
Line Segment. A fixed section of a line is called a line segment. A line segment has two endpoints, which are used to name it. For example, in the figure below, we have two points, X and Y. The section of the line from point X to point Y is line segment XY. The name of a line segment is given using capital letters.
Origin. The origin is a point where something begins or emanates from. In mathematics, the origin usually refers to a point on a number line or in a coordinate system. Number lines. On a number line, the origin is at position zero, as shown below: Each point on a number line corresponds to a real number and their positions relative to the origin.
