​​​​A regular dodecagon ($12$-sided regular polygon) is inscribed in a circle of radius $r$ cm as shown in the figure. The side of the dodecagon is $d \mathrm{~cm}$. All the triangles (numbered $1$ to $12$) in the figure are used to form squares of side $r \mathrm{~cm}$ and each numbered triangle is used only once to form a square.

The number of squares that can be formed and the number of triangles required to form each square, respectively, are:

Note: The figure shown is representative.

  1. $3 ; 4$
