Reflections
To view a reflection of the quadrilateral, check the box of the axis you would like to reflect the quadrilateral across.
Questions for Reflections:
1) Record the coordinates for Quadrilateral ABCD.
2) Check the box to reflect the quadrilateral ABCD across the x-axis. Record the new coordinates. Which coordinates (x or y) changed and how?
3) Can you write a math rule to describe what happens to the coordinates during a reflection across the x axis? (x, y) ( , )
4) Uncheck x and then check the box to reflect the quadrilateral ABCD across the y-axis. Record the new coordinates. Which coordinates (x or y) changed and how?
5) Can you write a math rule to describe what happens to the coordinates during a reflection across the y axis? (x, y) ( , )
6) Does a figure remain congruent when it is reflected?
