In a dilation, the size of a figure changes according to the scale factor, while the shape remains the same. Given a triangle ABC that is dilated with a scale factor of 5, centered at the origin (0, 0), the vertices of the triangle A, B, and C will be moved 5 times farther from the center of dilation (the origin) to create the new triangle A'B'C'.
Thus, the correct description of the dilation is:
Triangle A'B'C' is 5 times as large as triangle ABC and is 5 times farther from the center point of dilation.
This means that the new triangle A'B'C' will be larger than triangle ABC and will be positioned away from the origin by a factor of 5 compared to the original triangle.
