triangle efg is transformed to create triangle efg. which transformation occurred? translation stretch…

Brief Explanations:

Translation is moving a figure without rotation or reflection. A stretch changes the size. Rotation turns a figure around a point. Reflection flips a figure over a line. Here, the orientation of the triangle has changed, which is characteristic of a rotation. The shape and size remain the same, ruling out stretch. And it's not a simple slide (translation) or flip (reflection).

Answer:

rotation
