Reflecting Across the X and Y

Record the ordered pairs for each point of Rectangle ABCD Rectangle ABCD Points Reflection across the x-axis A(-5, -2) B(-3, -2) C(-3, -5) D(-5, -5) A B D C

Reflection across the x-axis Plot and label the reflection of each point across the x-axis. Connect the points to form a rectangle. Record the ordered pair of the reflection in the table you created. D C Rectangle ABCD Points Reflection across the x-axis A B A(-5, -2) B(-3, -2) C(-3, -5) D(-5, -5) A’(-5, 2) B’(-3, 2) A B C’(-3, 5) D’(-5, 5) D C How do the coordinates of an ordered pair change when the point is reflected across the x-axis? Explain.

When the point is reflected across the x-axis: x-coordinate stays the same y-coordinate changes sign (becomes the opposite) D C Rectangle ABCD Points Reflection across the x-axis A B A(-5, -2) B(-3, -2) C(-3, -5) D(-5, -5) A’(-5, 2) B’(-3, 2) A B C’(-3, 5) D’(-5, 5) D C

Reflection across the y-axis Plot and label the reflection of each point across the y-axis. Connect the points to form a rectangle. Record the ordered pair of the reflection in the table you created.
