How to use geometric sketchpad to fold triangles

php editor Xinyi introduces to you the operating techniques to achieve triangle folding in the geometric sketchpad. Triangular folding is an important step in making paper crafts and models, and requires correct operating skills. In Geometric Sketchpad, folding triangles can be achieved using a variety of methods, such as using line segments, angle tools, free drawing, etc. This article will introduce in detail the commonly used triangle folding methods to help you better operate Geometric Sketchpad.

1. Use the [Internal and Sided Polygon] button in the Polygon Tool of the Geometry Sketchpad (the second one in the Polygon Tool) to construct an arbitrary quadrilateral.

2. Use the point tool to draw three points A, B, and C in the drawing area. Select points A, B, and C in sequence, select [Construction] - [Arc passing through three points], and use the point tool to pick any point D on the arc.

3. Click the polygon tool. When point D on the arc becomes thicker, click the left mouse button. Similarly, when the corresponding point on the quadrilateral becomes thicker, click the mouse. Left click to get a triangle containing the interior. Drag point D to fold and flatten the triangle.
