Describe the dilation of triangle ABC, with a scale factor of 5 and a center point of dilation at the origin (0, 0).
Triangle A′B′C′ is 5 times as large as triangle ABC and is 5 times as far from the center point of dilation.
Triangle A′B′C′ is 5 times as large as triangle ABC and is 5 times closer to the center point of dilation.
Triangle A′B′C′ is 5 times smaller than triangle ABC and is 5 times closer to the center point of dilation.
Triangle A′B′C′ is 5 times smaller than triangle ABC and is 5 times as far from the center point of dilation.
