What kind of transformation is shown in the figure?
Let’s think about the different kinds of transformations that we know about. We know about reflections: when an image is reflected across a line, creating a mirror image like this. We know about rotations. This is when we turn an image around a centre point. We also know about translation, which means moving without rotating or resizing. In a translation, every point of the shape must move in the same direction and move the same distance.
Now, back to our figure, which of these transformations best explains what is happening to this shape? This is a translation. It has not been reflected or rotated. It has simply been moved to the right. It was not resized in anyway. We call this translation.
