Such a geek...pcad wrote:The angles of the blue and red triangles differ by about 1.25 degrees. They are both right triangles, but they are not similar triangles. In one case the apparent hypotenuse is bowed in and the other is bowed out. Clever illusion.
In addition the more acute angle of the 5x13 "triangle" is in between the blue and red angle. This makes it even harder to spot the differences.
Very clever!Paradox wrote:http://www.youtube.com/watch?v=w2Hr_5mseeI
