THE ANSWER IS EITHER OPTION B OR D EXPLAIN IF IT IS EITHER ONE

The areas of the squares created by the side lengths of the triangle are shown. Which best explains whether this triangle is a right triangle?

The set is 9, 12, and 15 

OR

One leg is 9...

Second leg is 12...

The hypotenuse is 15.....

Here are the options ( I only allowed to pick one answer )

Based on the converse of the Pythagorean theorem, the triangle is a right triangle because 9^2 + 12^2 = 15^2. ( what i picked ) 

Based on the converse of the Pythagorean theorem, the triangle is not a right triangle because 9 + 12 does not equal 15.

Based on the converse of the Pythagorean theorem, the triangle is not a right triangle because 9^2 + 12^2 does not equal 15^2. ( what I picked on my second try on the quiz )

Based on the converse of the Pythagorean theorem, the triangle is not a right triangle because 9 + 15 does not equal 12.
