Triangle Geometrical Paradox

[Steve Prevette]

And if you take the two triangles you have cut out, and overlay one on top of the other, you will see that the hypotenuses have two different slopes.

In paper cutouts you would have to be superman to see the difference, true enough. It's challenging enough in pixels.

How is that possible? I used a steel rule to define the slope(s). They have to be the same.

OK, my last response on this. Count the squares. The slopes are different on the two small triangles. Look at the wikipedia article and many many other internet writeups on this and other "dissection" puzzles that end up looking the same, but are subty different.
