Triangle ABC is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. Which statement describes the properties of triangles ABC and A"B"C" after the transformations?
O C and C" are congruent after both the translation and the dilation
OLC and C" are congruent after the dilation, but not after the translation
AC and A"C" are congruent after both the translation and the dilation.
O AC and A"C" are congruent after the dilation, but not after the translation
