... Competition (see CRUX [20:65]) goes as follows: An isosceles triangle is called an amoeba if it can be divided into two isosceles triangles by a straight cut. How many di erent (that is, not similar) amoebas are there? All three authors wrote that contest. Afterwards, they felt that the problem woul ...

Problem Set #3
... Consider OB and a point A on one side of OB . The ray of the form OA can be matched one to one with real numbers from 0 to 180. The measure of AOB is equal to the absolute value of the difference between the real numbers for OA and OB . ...

... began work on the fifth postulate in 1792 while only 15 years old, at first attempting to prove the parallels postulate from the other four. By 1813 he had made little progress and wrote: In the theory of parallels we are even now not further than Euclid. This is a shameful part of mathematics... Ho ...
