Transformations and similarity
When two figures are similar, the second shape has to equal up to the first one. For example, if a triangle was dilated from the original figure it has to equal up to the same size at the end. Or a figure could be dilated then translated or rotated, but in the end it still has to be the same as the original figure.
There are four forms of transformations. Their names are translation, dilation, reflection, and rotation. A translation slides the figure to s different place, while a reflection shows a mirror image. A rotation rotates the figure either 90, 180, or 270 degrees on the chart. last but not least, a dilation either makes the figure smaller or bigger. Which could have something to do with
