Consider the following five statements about similar matrices. (i) If A and B are similar matrices, then at least one of A and B is a triangular matrix. (ii) If A and B are similar matrices, then det(A) = det(B). (iii) If A and B are similar matrices, then A² and B² are similar. (iv) If A and B are similar matrices, then A and B have the same eigenvalues. (v) If A and B are similar matrices and A is symmetric, then B is symmetric.

Consider the following five statements about similar matrices.
(i) If A and B are similar matrices, then at least one of A and B is a triangular matrix.
(ii) If A and B are similar matrices, then det(A) = det(B).
(iii) If A and B are similar matrices, then A² and B² are similar.
(iv) If A and B are similar matrices, then A and B have the same eigenvalues.
(v) If A and B are similar matrices and A is symmetric, then B is symmetric.
Determine which which statements are true (1) or false (2) by testing out each statement on an appropriate
matrix.
