The operation process of drawing the rectangular coordinate system and drawing points on the geometric sketchpad

1. Establish a Cartesian coordinate system

Method 1 Directly open the system default coordinate system

Use [Define Coordinate System] in the [Drawing] menu to directly generate a Cartesian coordinate system. After opening the drawing tablet, click [Draw], and in the pop-up menu, click [Define Coordinate System]. This is the simplest method to establish a rectangular coordinate system.

Method 2: Use the coordinate system tool under the custom tool

In the geometric sketchpad, press and hold the custom tool button on the left with the mouse, and a shortcut will pop up Tool options include several coordinate system customization tools, such as new coordinate system, mini coordinate system, and classic coordinate system. You can also use these tools to quickly establish a plane rectangular coordinate system,

Method 3 Construct a plane rectangular coordinate system of arbitrary unit length

If we are not satisfied with the system's default unit length of the coordinate system, we can also freely set the unit length of the coordinate system to facilitate more accurate drawing.

2. Draw points in the coordinate system

After the coordinate system is established, you can draw points in the coordinate system. Points can be accurately drawn in the geometric sketchpad. Click [Draw] on the upper menu bar. 】menu, select the 【Draw Point】command in its drop-down option, as shown in the figure.

Enter the coordinates of the point. After executing the above command, a drawing point dialog box will pop up, in which you can directly enter the horizontal and vertical coordinates of the point, click [Draw], and a point will be drawn.

The above is the detailed content of The operation process of drawing the rectangular coordinate system and drawing points on the geometric sketchpad. For more information, please follow other related articles on the PHP Chinese website!
