ΔAʹBʹCʹ is a dilation of ΔABC with the origin as the center of dilation. The coordinates of the vertices are as follows: A (0.3, 1.2), Aʹ (1.8, 7.2) B (2.1, 3.1), Bʹ (12.6, 18.6) C (3, 2.1), Cʹ (18, 12.6) ABC has coordinates (0.3, 1.2), (2.1, 3.1), (3, 2.1). Triangle ABC (each letter with prime) has coordinates (1.8, 7.2), (12.6, 18.6), (18, 12.6). Determine the scale factor. What is the scale factor?

To find the scale factor u basically have to take 2 PAIRS of points (Example B (2.1, 3.1,) B’ (12.6, 18.6) and divide x two by x one so 12.6 divided by 2.1 and y two divided by y one 18.6 divided by 3.1. The answer should be 6.
