1 Prove That The Linear Transformation Represented By The Matrix M Is Rigid If And O 879367
1. Prove that the linear transformation represented by the matrix M is rigid if and only if MT = M−1.
2. Show that the linear transformation represented by the matrix M is orientation-preserving if and only if det (M) > 0.[
3. Figure II.9 shows an affine transformation acting on an F.
(a) Is this a linear transformation? Why or why not?
(b) Give a 3 × 3 matrix that represents the affine transformation.
