Shapes on grid

In this page, we have to reconstitute shapes respecting the grid. There are 3 parts.

In the first 2, we don’t use RayMag 9a

1) Small areas :

                  

      

2) Areas 108 :

This corresponds to the area of 12 basic triangles ; among the possible shapes, there are therefore the 3 334 dodecaiamonds, among which this one :

We can try these 3 334 shapes at levels 2, 3 or 4.

There are moreover those shapes which have at least one solution at level 3 :

3) Areas 117 :

This corresponds to the area of 13 basic triangles ; among the possible shapes, there are therefore the 9 235 tridecaiamonds, among which this one :

We can try these 9 235 shapes (at level 2 of course).

There are moreover those shapes which have at least one solution :
