**An equilateral triangle has 4-inch sides. Describe its image for a dilation with**

**scale factor 2.5. Explain.**

**Answer:**

An equilateral triangle with 10-inch sides.

Explanation: 4 * 2.5 = 10

^ The transformed triangle will have congruent sides of length 10, instead of its pre-image, which had sides of length 4. This is simply because the length of 4 is *scaled* by *2.5*, so 4 * 2.5 = 10.
