ira [324]

Answer:

  It is similar to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8)

Step-by-step explanation:

Dilated triangles are <em>never congruent</em>, only <em>similar</em> (unless the dilation factor is exactly 1).

The coordinates of an image dilated about the origin are those of the pre-image multiplied by the dilation factor. For example,

  A' = 2A

  A'(8, -12) = 2×A(4, -6)

These facts are all you need to know to choose the correct answer (shown above).
