Understanding the Pythagorean Theorem

The video tutorial explores multiple proofs of the Pythagorean theorem. It begins with constructing a right triangle and then rotates it to form congruent triangles. By constructing parallelograms and analyzing their areas, the tutorial demonstrates that the sum of the squares of the two shorter sides equals the square of the hypotenuse, thus proving the Pythagorean theorem.

What is the first step in constructing the right triangle for the Pythagorean theorem proof?

• Drawing the hypotenuse on the top

• Drawing the hypotenuse on the bottom

• Drawing the hypotenuse on the right

• Drawing the hypotenuse on the left
