The dashed triangle is smaller than the solid triangle,
so the dilation is a reduction.
Answer: The dilation is a reduction.
To find the scale, we find two corresponding points whose distances from the origin are easy to tell.
Let's use point (6, 0) on the original triangle and point (2, 0) on the dilation.
Point (6, 0) is 6 units from the origin.
Point (2, 0) is 2 units from the origin.
We divide the distance in the dilation by the corresponding distance in the original to find the scale factor.
2/6 = 1/3
Answer: The scale factor is 1/3.
