An enlargement makes a shape bigger or smaller from a fixed centre point, using a scale factor - exactly like pinch-zooming a photo on a phone, anchored at one spot.
Scale factor > 1: shape gets bigger. Between 0 and 1: shape gets smaller. Negative: shape flips through the centre too.
Example: Enlarging point (2,3) by scale factor 2 from the origin: new point = (2×2, 2×3) = (4,6).
