<span>To prove the Pythagorean Theorem based on similarity of triangles, you can always use the 2nd construction.
The 2nd construction is achieved by drawing a perpendicular line joining between the right angle of the triangle and the hypothesis (as shown in the attachment).
Note: The Pythagorean Theorm is stated as follows:
(length of hypotenuse)^2 = (length of side1)^2 + (length of side2)^2</span>
The formula of this ion is CrO42– . The correct option among all the options that are given in the question is the third option or the last option. The other choices are incorrect and can be easily negated. I hope that this is the answer that you were looking for and the answer has come to your desired help.
