- The image displays a net for a D20, which is a regular icosahedron, a polyhedron with 20 identical equilateral triangular faces.
- To solve the problem of assembling this net into a three-dimensional shape, you must fold along the edges where the triangles meet.
- Start by identifying a central triangle and fold its adjacent triangles upwards to form the first vertex of the icosahedron.
- Continue folding neighboring triangles so that their edges align and meet at vertices. Each vertex of a regular icosahedron is formed by five triangular faces meeting.
- Use glue or tape on the tabs (if present) or along the outermost edges to secure the shape once all folds are made and the structure closes properly.
- The final assembled object will be a symmetrical, convex polyhedron with 20 triangular faces, 30 edges, and 12 vertices — the standard shape of a twenty-sided die.
