TO ALL MY INTELLIGENT READERS...
I am publishing this only to my smart readers. I could not figure it out.
My first thought was wrong and I had to look at the answer.
See if you can figure out what these seven words all have in common?
Are you peeking or have you already given up?
Give it another try....
Look at each word carefully. You'll kick yourself when you discover the answer. This is so cool.....
No, it is not that they all have at least
2 double letters....
Let me know if you found the answer - I didn't!
Answer is below!
In all of the words listed, if you take the first letter, place it at the end of the word, and then spell the word backwards, it will be the same word. Did you figure it out? No? Then SHARE this to more people and stump them as well. Then, you'll feel better too.

The Pythagorean theorem is one of the most famous in all of mathematics.
Theorem: The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the legs.
There are many different proofs of the theorem (even one supplied by President Garfield in 1876!), and we know that the Babylonians knew about the Pythagorean theorem about 1000 years before the time of Pythagoras (born in 572 B.C.). Nonetheless, a rigorous, general proof of the theorem requires the development of deductive geometry, and thus it is thought that Pythagoras probably supplied the first proof. Most math historians credit him with a proof by dissection, which relies on the use of two squares, one inscribed inside the other. The Indian astronomer Bhaskara (1114-1185) developed this proof:
