The figure shows a smaller square with sides of length y inscribed in a larger square with sides of length x. Which of the following relationships between x, y, and z must be true ?
A. \(x^2 = y^2 + z^2\)
B. \(x^2 = y^2 - z^2\)
C. \((x-z)^2 = y^2\)
D. \((x-y)^2 = z^2\)
E. \((x-z)^2 + z^2 = y^2\)

Show: :: OA
OA in 24h
Here
we can write as the attached diagram
Now since it is square and all angles are right angle triangle
therefore by Pythagoras theorem ; y is the hypotenuse and x and (x-z) are the two legs of the triangle
\((x-z)^2 + z^2 = y^2\) ; which is option E
