alleryThe transpose of $A^T$ is:
A$A$, since transposing twice returns the original on chart
B$A^{-1}$, the inverse of the matrix on the school chart
C$-A$, the negative of the original matrix here always
D$2A$, twice the matrix value on the school chart here
Answer & Solution
Correct answer: A. $A$, since transposing twice returns the original on chart
$(A^T)^T = A$, transposing twice returns the original.
