triangle def is similar to triangle def. which similarity transformation could map △def to △def? dilation…

Brief Explanations:

Similar triangles can have different sizes and orientations. Dilation changes the size and rotation changes the orientation. A dilation and rotation can map one similar - triangle to another. A reflection would flip the triangle over a line, which is not indicated here as the orientation of the angles and vertices relative to each other is consistent with rotation and dilation. A translation just moves the triangle without changing its orientation or size, and it alone cannot account for the change in size and orientation seen here.

Answer:

rotation and dilation
