A. The if part and the then part switch places.

The correct statement that explains the Pythagorean theorem is A. "If a triangle is a right triangle, then the sum of the squares of the legs is equal to the square of the hypotenuse."

To understand the Pythagorean theorem, it helps to visualize a right triangle, which is a triangle with one of its angles measuring 90 degrees (a right angle). In a right triangle, the two sides that form the right angle are called the legs, and the side opposite the right angle is called the hypotenuse.

The Pythagorean theorem states that the sum of the squares of the length of the legs is equal to the square of the length of the hypotenuse. Mathematically, it can be written as:

a^2 + b^2 = c^2

Where 'a' and 'b' represent the lengths of the legs, and 'c' represents the length of the hypotenuse.

So, option A accurately explains the Pythagorean theorem.
