Complete the sentences to finish the explanation of how you could show that all squares are similar. Draw a square on a coordinate plane with vertices at (0, 0), (0, ), (a, a), and (a, ). Draw another square with vertices at (0, 0), (0, ), (b, b), and (b, ). Explain that these two squares can represent any two squares. Then show that there is a that maps one square to the other, so all squares are similar. At DEFG is a parallelogram.
