Given: A similarity transformation of triangle ABC to DEF as follows:
Required: Dilation factor of triangle ABC to transform triangle DEF.
Explanation: Triangle ABC is similar to triangle DEF.
AB is 2 units and DE is 1 unit.
So DE is actually half of AB.
Thus, triangle ABC is dilated by a factor of half.
So dialation factor is 1/2.
Final Answer: Option B is correct answer.
