Enigma/Paper Enigma - Franklin Heath Ltd Wiki. Although the Enigma cipher as a whole is quite complex (it's complexity is comparable to modern cryptographic algorithms) the individual transformations within it are relatively simple.
In fact, they are simple enough that you can decipher an Enigma message with just a paper model. Our model is three-dimensional, to illustrate the wiring of a real Enigma machine. It needs only common household items to construct, and is completely compatible with all settings of a real Enigma machine (models I, M1, M2 and M3). Materials Needed You will need these PDF templates printed on to 2 A4 sheets of paper, a crisp tube (75mm in diameter and at least 225mm long), clear sticky tape and a pair of scissors. Using low-tack "removable" sticky tape can make it easier to swap round and reuse the rotors if you want to do that, but it's not essential. Before you print the templates, please make sure you turn off any scaling options in your printer software so that it is printed at the exact size required. Bottle Rockets.

(They are still similar even if one is rotated, or one is a mirror image of the other). Try this Drag any orange dot at either triangle's vertex. Both triangles will change shape and remain similar to each other. Triangles are similar if they have the same shape, but not necessarily the same size. You can think of it as "zooming in" or out making the triangle bigger or smaller, but keeping its basic shape. Which is read as "Triangle PQR is similar to triangle P'Q'R' ".
Properties of Similar Triangles Corresponding angles are congruent (same measure)So in the figure above, the angle P=P', Q=Q', and R=R'. Rotation One triangle can be rotated, but as long as they are the same shape, the triangles are still similar. In this particular example, the triangles are the same size, so they are also congruent.
