Question

triangle abc is similar to triangle abc. which sequence of similar transformations could map △abc onto △abc? ○ dilation and reflection ○ dilation and translation ○ translation and rotation ○ translation and reflection

Explanation:

Step1: Analyze size difference

$\triangle A'B'C'$ is larger than $\triangle ABC$, so a dilation (scaling) is needed to change the size.

Step2: Analyze position/transformation

After dilation, a translation (moving) can align the triangles, as reflection or rotation don't match the orientation and position change shown. Rotation and reflection without dilation wouldn't change size, and translation/reflection without dilation also don't address size. So dilation (to enlarge) and translation (to move) are the transformations.

Answer:

dilation and translation (the option: dilation and translation)
