To dilate an object by a scale factor of 1/4, you need to multiply the coordinates of each point of the object by 1/4.
Let's say you have a point (x, y) that you want to dilate. The dilated coordinates would be:
(x', y') = (1/4 * x, 1/4 * y)
For example, if you have a triangle with vertices (2, 4), (6, 8), and (4, 10), and you want to dilate it by a scale factor of 1/4, the dilated triangle would have vertices:
(1/4 * 2, 1/4 * 4) = (0.5, 1)
(1/4 * 6, 1/4 * 8) = (1.5, 2)
(1/4 * 4, 1/4 * 10) = (1, 2.5)
So the dilated triangle would have vertices (0.5, 1), (1.5, 2), and (1, 2.5).
