U2 L6   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

Reflections Reverse Orientation

Important Facts!!
