The spidrosquare, as the spidron, have been created by Daniel Erdély ; if you want to see how it is made , click here.
The polyspidrosquares are assemblies of spidrosquares ; below a spidrosquare (orange) and the 7 bispidrosquares :
Below the 33 trispidrosquares :
4 spidrosquares allows us to make a square :
We take the area of this square as unit ; so the area of a spidrosquare is ¼ ; the area of a bispidrosquare is ½ and the area of a trispidrosquare is ¾ .
Here are shapes to realize :
I have several solves but I give only the 2 below :
Now play !
