## Understanding Dilations and Similarity

Dilations and similarity are two important concepts in geometry. A dilation is a transformation that enlarges or reduces an object. It is a scaling transformation that changes the size of an object, but not its shape or orientation. Similarity is a special type of dilation in which two objects have the same shape but different sizes. It is important to understand how to identify dilations and similarities in order to answer questions related to these transformations.

## Identifying Dilations and Similarity

In order to identify dilations and similarities, it is important to pay attention to the size, shape, and orientation of the objects. If two objects have the same size and shape, but different orientations, then they are not similar. If two objects have the same size and orientation, but different shapes, then they are not similar. If two objects have different sizes and shapes, but the same orientation, then they are similar.

## Example of Dilations and Similarity

One example of dilations and similarity is a circle and an ellipse. The circle and the ellipse have different sizes, but the same shape and orientation. Therefore, they are similar. Another example is a square and a rectangle. The square and the rectangle have different sizes, but the same shape and orientation. Therefore, they are similar.

## Using Dilations and Similarity Answer Keys
