The sign of the determinant measures whether the transformation T is orientation-preserving or orientation-reversing. (When the determinant is negative - e.g. if one selects the "Reflection" matrix example - try drawing an anticlockwise loop on the domain. A transformation is invertible when its associated matrix is invertible; that is, when it has a nonzero determinant. The orientation of the images on the plane are preserved with the determinant is positive, and the area is preserved when the determinant is -1 or 1. Using the Applet Example 1: Interpret for the matrix representing a reflection over the x-axis, . From here, . The magnitude of this is 1, indicating that the area of an image of an object reflected over the line is 1 times the area of the pre-image—an obviously true fact because reflections preserve area.
