Triangle J′K′L′ shown on the grid below is a dilation of triangle JKL using the origin as the center of dilation: Two triangles are drawn on a grid. First triangle has vertices J (6,12), K(9,6), L(12,9). Image triangle has vertices J' (2,4), K'(3,2), L' (4,3)


since the center of dilation is the origin, you can simply divide the coordinates of J', K', and L' over the coordinates of J, K, and L. for example, apply this logic to J at (6,12) and J' at (2,4) note that the previously posted answer of 1/2 is incorrect
