In the Pythagorean relationship,
The square of the hypotenuse is equal to the sum of the squares of the legs of the right angle
From the given figure
The hypotenuse is P
The two legs of the right angle are q and r
Then the Pythagorean relationship should be
[tex]p^2=r^2+q^2[/tex]Then she is not correct because she put r as the hypotenuse of the triangle and p, q are the legs of the right angle.
