How to draw a rectangular coordinate system using geometric sketchpad

Operation method one: directly open the system default coordinate system

After opening the geometric sketchpad, click [Drawing], and in the pop-up menu, click [Define Coordinate System]. This is the simplest method.

Operation method two: Construct a rectangular coordinate system of any unit length

Take the unit length as 2.5 cm as an example:

1. Use the translation command Construct point B. Use the point tool to draw a point A, select it and click [Transform] - [Translate]. After entering 2.5 in the [Fixed Distance] column in the translation window, click [Translation] in the lower right corner of the dialog box to get another point B.

2. Construct the line segment and define the unit length. Select point A and point B, click [Line Segment] under the [Construction] menu, and create a 2.5 cm long line segment AB. Select [Define unit length] under the [Drawing] menu to establish a coordinate system with a unit length of 2.5 cm.

3. Hide line segment AB. Select the line segment and two endpoints, and select [Hide Object] in [Show].
