Which of the following terms describes a size-changing transformation that can resize figures either up or down while preserving their shape?

Explanation:
Scaling is a resizing transformation that keeps the shape the same. Imagine shrinking or enlarging about a fixed center: every distance from that center is multiplied by the same factor. If the factor is greater than 1, the figure grows; if it is between 0 and 1, the figure shrinks. Angles stay the same, so the figure remains similar in shape. Rotation and reflection change orientation but keep the size, so they don’t resize. Enlargement is a case of scaling where you enlarge (factor > 1), but scaling covers both up and down, which is why it’s the best term for describing a size-changing transformation that preserves shape.
