DO NOW!!

Define perpendicular bisector.

The perpendicular bisector is a line that divides a line segment into two equal parts. It also makes a right angle with the line segment.

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.
