The Tangram (Chinese game meaning "seven boards of skill") is a dissection puzzle consisting of seven flat shapes, called tans, which are put together to form shapes. The objective of the puzzle is to form a specific shape (given only an outline or silhouette) using all seven pieces, which may not overlap.
Choosing a unit of measurement so that the seven pieces can be assembled to form a square of side one unit and having area one square unit, the seven pieces are:
• 2 large right triangles
• 1 medium right triangle
• 2 small right triangle
• 1 square
• 1 parallelogram
Of these seven pieces, the parallelogram is unique in that it has no reflection symmetry but only rotational symmetry, and so its mirror image can be obtained only by flipping it over. Thus, it is the only piece that may need to be flipped when forming certain shapes.
Step 1: Material Required
I have used thick white cardboard. And for attaching the pieces together, one can use nut bolts and shafts (like shown in the picture).
I have made the shafts with the same cardboard (you can also try finding them in the market, if you don't want to make them). I've made the shafts by cutting the cardboard in these shapes and punching both the corners (easy and quick)!
Step 2: How to Make These Shapes?
Once you've cut the pieces, single punch the corners of all. This will help later for fixing them together!
Step 3: How to Convert These 2D Shapes Into 3D?
Height can be easily giving by cutting flat shapes and attaching on the sides of the previously cut Tangram shapes.
Step 4: How to Fix These Together?
I have explained how to make the shafts in step 2.
Now, all you need to do is start holding the pieces in the desirable shape and way you want, insert the nut from the inside of the depth of shape ..shaft both the pieces together and bolt them. Continue the same step for all the shapes until you achieve the desirable form!
The one I've made here is a sitting cat :)
Step 5: Ready to Use :)
Step 6: Bored? Change the Shape!
I have created a few 3DS models for you to see.. Rest, creativity has no limits!
Explore materials! Explore shapes!
Step 7: The Mini Organizer :)
Step 8: How to Add Secret Compartment?
- Punch this as well, exactly like the base.
- Hide you stuff (money etc.)
- Close it the duplicate shape you've made
- Nail the sides (I've used rivettes for this one since they're more easy to use)
