In four sentences, describe the process, you could use to determine if a shape is a reflection of a Preimage. What feature should stay the same and what should change from the preimage to the image? Give an example.

Answer 1

To determine if a shape is a reflection of a Preimage, the key is to look for two main features: symmetry and orientation. The shape should have symmetry with respect to a line of reflection such that the two halves on either side of the line are mirror images of each other. Additionally, the orientation of the shape should be reversed from the preimage, meaning that the shape should be flipped across the line of reflection. For example, if the preimage is a triangle with vertices at (0, 0), (2, 0), and (1, 3), its reflection would be a triangle with vertices at (0, 0), (-2, 0), and (-1, 3). The symmetry is seen across the x-axis, and the orientation is reversed.
