Line of Reflection
A point in the image and its corresponding point in the pre-image are equidistant from the line of reflection
All the lines connecting points in
the image with points in the
pre-image are perpendicular to
the line of reflection
5
Open Ended
According to the definition, is this a reflection? Explain.
6
Orientation
Clockwise (CW) vs. Counterclockwise (CCW)
What happens to the orientation of the pre-image points when they are reflected?
7
Open Ended
What is the equation of the line of reflection?

Multiple Choice
When you reflect a figure across the y-axis, the vertical height of each point is unchanged, but the horizontal value of the image is the opposite of the pre-image. (x, y)→
