It appears that Pythagoras didn't discover it, as it was known to the Babylonians before his time.
Pythagoras founded a group (called the Pythagoreans). The contribution of this group to what is now called Pythagoras's Theorem seems to have been to state it in a general form, and maybe to attempt a proof of it. Unfortunately there is essentially no evidence surviving for who did what in the group, or when.
Pythagoras founded his group in a place called Croton (in Italy), but he and his followers were eventually driven out, and went to various places. Also Pythagoras travelled around before he went to Croton. So we don't even know with certainty where the work by the Pythagoreans on the triangle property was done, thouogh Croton would be a reasonable guess, as far as we know.

Yes, it's called Pythagoras theorem
Pythagoras discovered that a scalene triangle is in fact a square
No but traditionally it is accredited to him
Euclid and Pythagoras.
Discover of a Mathematical formula to relate the sides of a right triangle.
Pythagoras' theorem states that for any right angle triangle that the square of its hypotenuse is equal to the sum of its squared sides.
Pythagoras discovered that for any right angle triangle its hypotenuse when squared is equal to the sum of its squared sides.
We use Pythagoras property to find the length of the third side, when two sides of a right-angled triangle are given by the following formula: In a right triangle, Square of hypotenuse = sum of squares of other two sides.
Pythagoras property or Pythagorean property tells us that in a right triangle, the square of hypotenuse is equal to the sum of the squares of the other two sides.
It is used to find the hypotenuse of a Right triangle (hypotenuse)2= (side1)2 + (side2)2
Pythagoras theorem will always work with a right-angled triangle.
