Rotation Method
 (Tessellations)
 1. Draw a square (Solid rectangle + Shift). 2. Click on the color red and on curved line and draw a line from the lower left-hand corner to the lower right-hand corner.  Pull on the line upward and click twice to set the arc of the curve.  (Using the curved line requires that you set the arc of each curve twice by clicking twice. If you do not want to use the curved line, then use the straight-line tool.) 3. Click on the dotted star and draw around the red line selecting the whole side. Copy the red line along with the bottom black line (Ctrl + C). Click on the lowest box on your tool bar. This causes the object to be transparent. Then paste the copy of the red line and black line (Ctrl + V) in a blank area.  Copy the red and black lines again (Ctrl + C). 4. Next while it still has dotted lines around it, click on Image, Flip/Rotate and Rotate by angle choosing 90° and OK.  Drag into place as in Figure 4 and click outside of the dotted lines to paste it.  This rotates the red line by 90° around point A. 5. Recopy Figure 3 (Ctrl + C).  To rotate around Point B click on Image, Flip/Rotate and Rotate by angle choosing 180° and OK.  Drag into place as in Figure 5 and click outside of the dotted lines to paste it.  For Point C recopy Figure 3 again (Ctrl + C).  Click on Image, Flip/Rotate and Rotate by angle choosing 270° and OK.  Drag into place as in Figure 5 and click outside of the dotted lines to paste it. (Note: In essence you have made a 90° rotation around each angle of the square.)  WARNING:  If any of the red lines overlap, the shape will not tessellate. Start over and redraw the shape so there are no overlapping lines. 6. Click on the color white and on the paint bucket. Fill the black lines with white to erase them. 7. Draw designs inside the shape and fill with colors.  Click on File, Save As, and name it flower1.  Copy Figure 7 by dragging the dotted rectangle around it and using Ctrl + C. Open a new screen using File and New. Paste the shape (Ctrl + V).  File, Save As, and name it flower2. 8. Paste the shape a second time (Ctrl + V).  While it is still selected (dotted lines around it), click on Image, Flip/Rotate and Rotate by angle choosing 90° and OK.  Drag into place as in Figure 8 and click outside of the dotted lines to paste it.  Paste the shape a third time (Ctrl + V).  Click on Image, Flip/Rotate and Rotate by angle choosing 180° and OK.  Drag into place as in Figure 8 and click outside of the dotted lines to paste it. Paste the shape a fourth time (Ctrl + V).  While it is still selected (dotted lines around it), click on Image, Flip/Rotate and Rotate by angle choosing 270° and OK.  Drag into place as in Figure 8 and click outside of the dotted lines to paste it.  Click on File and Save.  Using the dotted rectangle, drag around Figure 8 and copy it (Ctrl + C).  Click on File and New.  Paste it (Ctrl + V).  Then paste and drag into place repeatedly until you have filled up the page.
