Question

In 3–5 sentences, describe the process you could use to determine if a shape is a reflection of a preimage. What features should stay the same and what should change from the preimage to the image? Give an example.(4 points)

Answer 1

To determine if a shape is a reflection of a preimage, you can follow these steps:
1. Identify the corresponding points on the preimage and the image.
2. Measure the distance between the corresponding points to check if they are equal.
3. Check if the angles formed between the corresponding sides are congruent.
4. If the distances and angles remain the same, then the shape is a reflection of the preimage.

For example, if we have a square as a preimage with side lengths of 4 units, and its reflection has all the side lengths still measuring 4 units and the angles between the corresponding sides are congruent, then the shape is a reflection of the preimage.
