Kate Jones has just added pieces to her site that allow you to surround the shapes you are trying to reconstruct using the polyores of La Ora Stelo.

There are 3 new parts :

Below are the dimensions :

Dimensions 1 and φ refer to the dimensions of the triangles which serve as a basis for the polyores ; remember that φ is the golden ratio (about 1.618) :

Bord 1 and Bord φ are straight edges and Bord 36° is an angle-edge.

The angles of a convex shape made using polyores can only be 36 °, 72 °, 108 ° or 144 °; these angles are obtained by using respectively 4, 3, 2 or 1 angle-edges :

To familiarize yourself with these edges and, at the same time, with the polyores, I suggest exercises.

You can also choose to go directly to the challenges (défis in french).

A few words to present these challenges ; the shapes that you will have to reconstruct using polyores have a dimension denoted by .

In her pages, Kate Jones gives 148 possible values of . Here are the top 40 values :

They are arranged in ascending order ; to get an idea, here is the materialization of the first column using straight edges :

and that of the fourth column :

Here are 3 examples :

Regular pentagon series :

We give :

For each value of , you have to build the fence (example with = φ + 1) :
