Isometry

"Isometry" is a big word that means things that are basically the same shape and size, but might be in different places or facing different ways. Imagine you have a toy car that you really love. If you make a copy of that toy car using clay or play-doh and it's the exact same size as the original and it has all the same details and features, we can say that the two toy cars are isomorphic.

Now, let's say you pick up the original toy car and hold it in front of a mirror. In the mirror, the car looks like it's facing the opposite way. However, even though it looks different in the mirror, it's still the exact same size and shape, right? So we can say that the original toy car and its reflection in the mirror are isometric to each other.

Overall, "isometry" is a way of talking about things that are the same shape and size, regardless of how they are positioned or orientated.
