# Similarity and Transformation Lesson

When identifying similarity it is when two figures are similar if the second can be obtained from the first by a sequence of the **transformations** and **dilations**. **Transformations** is an operation that maps a geometric figure, preimage, onto a new figure, image. **Dilation** a transformation that enlarges** **or reduces the figure by a scale factor. The figure could also be reflected or rotated. **Reflection **means to flip the image over the x-axis or the the y-axis. On the other hand **rotation **means the figure is turned to a fixed point like 90 degrees, 180 degrees, or 270 degrees.

These are some examples of the **transformations** in the top left hand corner is **rotation** and the right top hand corner is **reflection**. Then in the bottom left corner is** dilation** and in the right hand corner is **translation**.

This video can help you understand what the 4 transformations are and what you do to get them. It helps you get an image of what the outcome might look like. **In the**__ video it says enlargements which is really dilation__.
