How to use geometric sketchpad to draw triangular coordinate system

Geometry Sketchpad is a powerful geometric drawing software that can draw various geometric figures. This article will introduce how to use the geometric sketchpad to draw a triangular coordinate system. The triangular coordinate system, also known as the three-line coordinate system, is used to determine the position of a certain point in space. It plays an important role in the study of space geometry and engineering calculations. Want to know how to draw a trigonometric coordinate system using Geometry Sketchpad? Read on!

Method 1: Use the coordinate system that comes with the Geometry Sketchpad

Click to open the Geometry Sketchpad, click [Define Coordinate System] in the [Drawing] menu above, and click [Draw] after defining the coordinate system Select [Coordinate Grid] - [Triangular Coordinate Grid] from the menu, and click [Yes] in the pop-up dialog box to establish the triangular coordinate system as shown in the figure.

Tip: After defining the coordinate system, you can also right-click on the drawing board and select [Triangular Coordinate Grid] to convert the x-axis into radians, as shown in the figure Show.

Method 2 Use Ant | Triangular Coordinate System

Step 1 Open the geometric sketchpad, click the [Custom Tools] button on the left sidebar, and in the pop-up Select [Classic Coordinate System] - [Ant | Triangular Coordinate System] from the tool menu, as shown in the figure.

Step 2 After selecting the above tools, click twice in the drawing board working area to draw the triangular coordinate system, as shown in the figure.

Step 3 The coordinate system at this time is quite messy and needs to be adjusted. Click the [Initialize] button to restore the coordinate system to its initial state, as shown in the figure.

The design in this coordinate system is relatively free. You can also click the [Grid Lines] button to hide the grid, and click the [Scale Marks] button to display the scales in this coordinate system. Line, click the [Standard Grid] button to adjust the grid to a square, click the [Console] button to hide the console of the coordinate system, and click the [Label] button to modify the scale value label.
