How to draw a rectangular grid using geometric sketchpad

The Dilemma of Drawing a Rectangular Grid: Making a rectangular grid in Geometry Sketchpad is not an easy task, but it is a useful tool for creating a variety of graphs and charts. Introduction to this article: In order to help you solve this problem easily, PHP editor Youzi will guide you step by step through the detailed process of drawing a rectangular grid in the geometric sketchpad. In this article, you'll learn how to set parameters, resize the grid, and export images.

Open the geometric sketchpad, execute the [Data]-[New Parameter] command, and in the pop-up dialog box, modify the parameter name to n, the value to 6, and the unit is none. Use the line segment tool to draw fixed line segments a and b as the length and width of the rectangle.

Draw a free point A on the plane and construct a rectangle ABCD based on the given line segments a and b. Measure the length of line segment a, and then execute the mark distance command to translate point A to construct the vertex D of the rectangle. Measure the length of line segment b, and then execute the mark distance command to translate point A to construct vertex B of the rectangle. Construct line segments AB and AD, draw the parallel line of line segment AB through point D, and draw the perpendicular line of the parallel line through point B to obtain the vertex C of the rectangle. Construct line segments BC and CD to obtain rectangle ABCD.

Select point A and parameter n=6, hold down the [Shift key], execute the [Transform]-[Depth Iteration] command, and press A→ in the pop-up dialog box B, A→D, A→C iteration, and then click the [Iteration] button.

In this way, the triangular mesh as shown in the figure is completed. Use the [] keys to control the parameter n and increase or decrease the number of meshes. .
