When a triangle undergoes dilation with a scale factor of 5 and a center point of dilation at the origin (0, 0), the resulting triangle \( A'B'C' \) will be 5 times larger than triangle \( ABC \). Additionally, each vertex of triangle \( A'B'C' \) will be located 5 times further from the center point of dilation compared to the corresponding vertex of triangle \( ABC \).
Therefore, the correct description of the dilation is:
Triangle \( A'B'C' \) is 5 times as large as triangle \( ABC \) and is 5 times as far from the center point of dilation.
