<human>:  Can you explain the Pythagorean Theorem?
<bot>: The Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two sides adjacent to the right angle is equal to the square of the length of the hypotenuse. In simple terms, it states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. For example, if the length of side A is 4, the length of side B is 3, then the length of the hypotenuse (side C) must be 5.
