Pentagon CDEFG was reflected over the y-axis to create a new figure. Which rule describes this transformation?
Responses
The rule that describes reflecting a figure over the y-axis is "y-axis reflection" or "reflection over the y-axis."
The rule that describes reflecting a figure over the y-axis is x = -x.
The rule that describes reflecting a figure over the y-axis is the "x-axis reflection" or "reflection over the x-axis" rule. If a point (x, y) is reflected over the y-axis, the resulting point will have coordinates (-x, y).
To apply this rule to the Pentagon CDEFG, you would reflect each vertex of the pentagon over the y-axis. For example, if the coordinates of point C were (x1, y1), the coordinates of the reflected point C' would be (-x1, y1). Similarly, the coordinates of the other vertices D', E', F', and G' would be (-x2, y2), (-x3, y3), (-x4, y4), and (-x5, y5), respectively.
By performing these reflections for each vertex, you will obtain the coordinates of the new figure resulting from reflecting the Pentagon CDEFG over the y-axis.
