Estimate the reflection of figures by reflecting one point at a time. Refine the estimate using a grid.
[i]Answer these open ended questions on your own or with others to form deeper math connections.[/i]
When reflecting a shape across a line, what aspects of that shape’s sides or angles change? What parts stay the same?
The segments that connect the corresponding points of a preimage and image, always seems to intersect the line of reflection. Describe the special type of intersection that occurs.
Observe the distance from a given point to the line of reflection. Then, observe the distance from the corresponding reflected point to the line of reflection. What do you notice about these distances?
Did seeing a grid make a difference in finding the reflected image? Explain why or why not.
