An equilateral triangle has 4-inch sides. Describe its image for a dilation with
scale factor 2.5. Explain.
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.
