1, sequence:
The order of rows is of great significance in plane geometry. When describing the arrangement and distribution of points, lines and surfaces on a plane, the order of rows determines their relative positions and directions. For example, in a coordinate system, the order of rows determines the lateral position of points. If the order of rows changes, the position of points and the direction of lines and planes will also change.
Although the order of columns has certain significance, it has less influence than rows. In a column, the order of elements or objects usually does not affect their vertical position and direction.
2. Directionality:
The direction of a row is usually related to the horizontal direction. On the map, the direction of lines is from left to right or from right to left, which is consistent with people's reading direction. In mathematics, people usually use the coordinate axis in the horizontal direction to describe the lateral position of a point.
The direction of the column is usually related to the vertical direction. When drawing a building or organization chart, the direction of the column is from top to bottom or from bottom to top, which is consistent with the direction of people's sight. In mathematics, people use the vertical coordinate axis to describe the vertical position of a point.
3. Independence:
The independence of the line is high. Put different elements or objects in a row, and there is no direct correlation or dependency between them. This means that one row can change, replace or add elements independently without affecting the elements of other rows. This independence makes it very convenient for rows to process data and organize information.
In contrast, the independence of columns is low. Elements or objects placed in columns are usually interrelated or interdependent. This means that elements in one column cannot be changed, replaced or added separately, otherwise elements in other columns may be affected. This dependence makes columns need to be more careful when dealing with data and organizing information.
4. Spatial distribution:
The spatial distribution of rows is usually related to the horizontal direction. When describing the arrangement and distribution on a plane, rows usually represent the arrangement in the horizontal direction. For example, when listing data in a table, rows represent different data items. This arrangement makes it very convenient for rows to display data and compare different data items.
The spatial distribution of columns is usually related to the vertical direction. Putting the same elements or objects in a column can make them orderly arranged vertically. For example, when drawing a chart, columns usually represent data of different categories or time periods. This arrangement makes the columns very intuitive when displaying data from different aspects or time periods.
Row and column are very important concepts in plane geometry, and they are obviously different in order, directionality, independence and spatial distribution. A correct understanding of the concepts of harmonious zone lines and columns can help people better describe and understand the arrangement and distribution of points, lines and planes in the plane.
