Technique of drawing square with oblique second method in geometry Sketchpad

Step one opens the geometry artboard and uses the line segment tool to draw the square abcd.

Step two draws the midpoint m of the segment AB, then the point M is centered with point A, rotates 45 degrees, gets the point M '.

Take the midpoint m of the line segment AB and get the point M ' sample by rotation

In the third step, select Point A, M, and then perform the tag vector operation. Select Points B, C, D, and then move them by the Shang of the markers to get points B ', C ', d '.

Step four uses the line segment tool to connect the segments to draw the edges of the squares.

Step five hides the point M and renames the point M ' to get the cube as shown in the following figure.
