Exploring Reflections

What does a reflection look like? Predict what the reflection of the polygon over line QR will look like, then check the box to perform the reflection. How does the reflected polygon compare to your prediction? Drag the line left and right. What happens to the reflection as the line moves closer to and further from the polygon? Uncheck the box and drag points Q and R to change the line. Can you predict what the reflection will look like? Check the box to see!
