Standard Shapes of Basic Moqarnas

Ali Reza Sarvdalir taught us that there are a few standard shapes. From left to right, five squares and three rhombuses. To be precise, the fourth one is half a square. This worksheet is part of my geogebra book on Muqarnas. More information is available on my website Muqarnas/Natanz .
