ELI5: Explain Like I'm 5

Point reflection

Point reflection is like making a picture look like a mirror image. Imagine you have a picture of a bird, and you want to make an exact copy of it, but flipped over like it's looking in a mirror. To do this, you need to pick a point in the middle of the picture, called the "reflection point." Then, you draw an invisible line through that point, and for every point on one side of the line, you find the matching point on the other side of the line that is the same distance away from the reflection point. Then, you draw a line connecting those two matching points, and that's the new mirror image of the original picture. It's like if you were standing in front of a real mirror and looking at yourself - everything you see in the mirror is flipped over, and that's what point reflection does to pictures.
