Dilation Section 2.7
Definition • A transformation that makes a figure larger or smaller. • Therefore since we change the size, the image is SIMILAR to the original
(x, y) • Multiplying both (x, y) by a constant number, k • If k = 5 (2, 7) (10, 35) If k = ¼ (4, 16) (1, 4)
Types • If k > 1 • ENLARGEMENT (BIGGER) If k < 1 - REDUCTION (SMALLER)
