<s>[INST] Explain the logic behind the Pythagorean theorem. [/INST] the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.</s>\ <s>[INST] I'm a little confused. Do you mean, a^2 + b^2 = c^2, c being the length of the hypotenuse? [/INST] you are correct, however, may I ask what is confusing so I can further assist you?</s>
