In the composition of a translation followed by a dilation, the following properties are preserved and not preserved:

  1. Angle Measure: This property is preserved. Both translation and dilation do not change the measures of angles.

  2. Distance: This property is not preserved. While translation does preserve distances, dilation changes distances by a scaling factor.

  3. Shape: The shape of the rectangle is preserved through both transformations, as dilations maintain similarity (the same shape, but possibly different size).

  4. Orientation: The orientation of the rectangle can change depending on the center of dilation. If the dilation is centered at a point outside the rectangle, it may flip the orientation.

Based on this, the properties not preserved after the composition transformation are:

  • Distance (due to dilation)
  • Orientation (can change depending on dilation's center)

Thus, the answer to the question is distance and orientation.
