Summary

  • Orthogonal Matrix What is an Orthogonal Matrix?
  • In terms of geometry, orthogonal means that two vectors are perpendicular to each other.
  • Additionally you may select any two rows and find that the same property holds, as the transpose of an orthogonal matrix is itself an orthogonal matrix.
  • Because the transpose preserves the determinant, it is easy to show that the determinant of an orthogonal matrix must be equal to 1 or -1.
