What is a Transformation? | Printable Summary

In a reflection, we flip a figure over a line of reflection to create a mirror image
The new figure that is created after any transformation is called the image
In a translation, we slide or move a figure to a new location in the coordinate plane
In a dilation, we increase or decrease the size of the original figure
In a rotation, we rotate a figure around a point in the coordinate plane

1. The line of reflection is the line we flip the figure over
2. In our example, the line of reflection is the x-axis
1. The image is the figure we get after performing ANY transformation, not just reflections
1. Translations can be horizontal slides, vertical slides, or a combination of the two
1. In our example, we are rotating the figure 90 degrees around the origin
