Triangle PQR is the image of triangle JKL after a dilation. Is the dilation an enlargement or a reduction? Explain.

• Enlargement, because the image is larger than the original figure.

• Enlargement, because the image is smaller than the original figure.

• Reduction, because the image is smaller than the original figure.

• Reduction, because the image is larger than the original figure.
