Prove that, at a recent convention of biophysicists, the number of scientists in attendance who shook hands an odd number of times is even. The same problem can be expressed graphically as follows: ...

Upon observation we notice, Shape A matches Shape B when rotate it clockwise 90 degrees. Similarly, when we rotate Shape B clockwise 90 degrees, it matches Shape C. Applying same logic, when we rotate ...
