Question

identify the transformation that took place. a rotation, b translation, c reflection, d dilation

Explanation:

To identify the transformation, we analyze the two triangles (red and purple). A reflection is a flip over a line (like the x - axis here, as the y - coordinates of corresponding points seem to be mirrored). Rotation would involve turning around a point, translation is sliding, and dilation is resizing. Here, the triangles appear to be flipped over the x - axis, so it's a reflection.

Answer:

c. reflection
