What is the Pythagorean Theorem?
The Pythagoras Theorem is also referred to as the Pythagorean Theorem
Pythagorean Theorem is used to find a side of any right triangle. It is 
, where 
and 
are the legs of the triangle, and 
is the hypotenuse.
Why is it useful?
To find sides and angles of right triangles. Also, Trigonometry is pointless without it. If you know three angles of a triangle you can use the Pythagorean Theorem to find the sides or the area even if the angles are not right. It is probably the most famous Theorem in all of math!
Can we prove it?
Yes! The are hundreds of proves. I will just show you a few of them. Mathematicians even make a hobby of finding these proves. Even a US president made a published proof! Of, course this was a president in the 1800s because, well, presidents now are not really up to proving something like that. (You know, Trump and the others).
