George has a triangle-shaped garden in his backyard. he drew a model of this garden on a coordinate grid with vertices a(4, 2), b(2, 4), and c(6, 4). he wants to create another, similar-shaped garden, a? b? c? , by dilating triangle abc by a scale factor of 0.5. what are the coordinates of triangle a? b? c? ? a. a? (2, 2), b? (1, 2), c? (3, 2) b. a? (2, 1), b? (1, 2), c? (3, 2) c. a? (8, 4), b? (4, 8), c? (12, 8) d. a? (2, 1), b? (1, 2), c? (6, 4)
