The dodecahedron is a multifaceted geometric figure that consists of twelve pentagons. Each three pentagons form one of the vertices of this intricate shape. Today, the dodecahedron is often used in the manufacture of various souvenirs and calendars.
It is necessary
- - dodecahedron layout;
- - scissors;
- - ruler;
- - glue;
- - marker;
- - cardboard;
- - pencil;
- - paper;
- - paper clips.
Instructions
Step 1
Buy ready-made dodecahedron-shaped calendars and assemble them. It is not difficult to get such a figure. Carefully cut the shapes along the marked boundaries. Then, using a ruler, fold the dodecahedron at its folds (they are shown with a dotted line) and glue. Mask all sorts of scuffs and small visual defects with a marker of the appropriate color.
Step 2
Make a dodecahedron. To get started, fold the Whatman paper in half with a slight oblique slope. On one piece of cardboard, draw a pentagon in the middle, and then draw another pentagon from each edge. This will end up with six pentagons drawn. Perekolit your masterpiece on the second part of the Whatman paper and draw the exact same figure. Then mark the gluing points. When the main work is completed, cut out the layout, color and glue it.
Step 3
Buy thirty sheets of paper (you can use three colors of paper for beauty). Take three sheets of paper and make modules out of them. To do this, fold the sheet in half, after which each half again in half (in the opposite directions). That is, the result should be a fan. Fold each side squarely and the module slightly obliquely. A separate trefoil module is the top of your dodecahedron. Continue building with the remaining twenty-seven sheets. Only at the end of the assembly will the figure become stable, so during creativity, use paper clips for greater convenience.
