This is a TRUE-FALSE Question with justification. If Q is an orthogonal n×n matrix, then Row(Q) = Col(Q). The Answer to this is TRUE. I want to know a solid reasoning/explanation for it. In one of the answers, it says that " Since Q is orthogonal, QTQ = I, so Q is invertible, hence Row(Q) = Col(Q) = Rn. But my question is: Why is it that for an invertible matrix, Row(Q) = Col (Q) ? Any other explanation that...
