Draw a free point A on the plane and construct a square ABCD with the given side length a. Measure the length of line segment a, and then execute the mark distance command to translate point A to construct two vertices B and D of the square. 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. The intersection point is C. Hide the parallel lines and perpendicular lines. Construct line segments BC and CD to obtain square ABCD.

Tip: The iteration depth of the geometric sketchpad is limited. The more images there are, the shallower the iteration depth is. Therefore, when we apply iteration, we should first estimate your iteration. Whether the number of times is within a reasonable range, otherwise the expected effect will not be achieved. At this time, multiple images should be resolved into low-order images as much as possible to increase the iteration depth.
