Triangle abc with vertices a(4, −6), b(2, −8), and c(−10, 4) is dilated by a scale factor of 2 to obtain triangle a′b′c′. which statement best describes triangle a′b′c′? (5 points)

it is similar to triangle abc and has coordinates a′(2, −3), b′(1, −4), and c′(−5, 2).
it is similar to triangle abc and has coordinates a′(8, −12), b′(4, −16), and c′(−20, 8).
it is congruent to triangle abc and has coordinates a′(2, −3), b′(1, −4), and c′(−5, 2).
it is congruent to triangle abc and has coordinates a′(8, −12), b′(4, −16), and c′(−20, 8).

  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 never congruent, only similar (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).
