The Pythagorean theorem uses the right triangle.
President James Garfield was one famous person who proved it.
The Pythagorean Theorem is not a triangle. It's a statement that describes a relationship among the lengths of the sides in any right triangle.
The Pythagorean Theorem allows the mathematician to determine the value of the hypotenuse. The converse of the Pythagorean Theorem manipulates the formula so that the mathematician can use the values to determine that if the triangle is a right triangle.

James A. Garfield, the twentieth president of the United States, discovered an original proof of the Pythagorean theorem. The proof is algebraic in nature and uses the formula for the area of a trapezoid. See the link below for details. Garfield is credited with an original proof of this famous theorem. Many of the presidents undoubtedly proved it in geometry class after studying their books.
The Pythagorean Theorem states that in a right triangle with legs a and b and hypotenuse c, a2 + b2 = c2. The converse of the Pythagorean theorem states that, if in a triangle with sides a, b, c, a2 + b2 = c2 then the triangle is right and the angle opposite side c is a right angle.
any right triangle
James Garfield is the only president credited with an original proof of the Pythagorean Theorem.An educated guess is that most of the college educated presidents knew a proof of this theorem at one time in their schooling.
Somewhere around 1875 and 1876
the sides of a triangle on which the Pythagorean theorem can be applied is called Pythagorean triplet
