U2 L4 Reflections
Reflections each preimage has an image that is the same distance from the line of the reflection as the original point but in the opposite direction. The image of any point on the reflection line is itself.
The Reflection Line is the Perpendicular Bisector of the segment connecting a preimage with its image.
Reflections Preserve Distance and Angle Measure
