Proposition 2.20. Let T : H + K be a linear operator and let {41, U2, ..., Uk} be an orthonormal basis for H. Then the following are true: (i) T is an isometry if and only if {Tu1,Tu2, ..., Tux} is an orthonormal set in K. (ii) T is unitary if and only if {Tuj, Tu2, ..., Tuk} is an or- thonormal basis for K. Proof. Exercise 7.
