Procedure:

1. First click on the GeoGebra icon from the desktop

2.  Click on the button near to the graphics to make the blank page. 

3. Click to grid and axes to hide the grid                     and axes.

7. Click to a perpendicular line tool to draw a perpendicular line

8. Click on the line drawn in step 6 to draw a perpendicular line. (After clicking drag a line to point

9. From point B draw a circle through point A using the Circle with Centre through a Point tool

10. Now add a new point C on the intersection point.

11. Repeat step 8 to draw a perpendicular line. (This time drag a line to point A)

12. From A draw a circle through B using the Circle with Centre through a Point tool

13. Now add a new point D on the intersection point

 14. Now click polygon tool and click on the point A and drag the line to point B then to point C and finally to point D to make a square.
