  1. Pythagorean theorem - Wikipedia

    • In mathematics, the Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. The … See more

    StatementThe sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c).
    Proofs using constructed squares

    In one rearrangement proof, two squares are used whose sides have a measure of and which contain four right triangles whose sides are a, b and c, with the hypotenuse being c. In the square on the right side, t… See more

    Other proofs of the theorem

    This theorem may have more known proofs than any other (the law of quadratic reciprocity being another contender for that distinction); the book The Pythagorean Proposition contains 370 proofs.
