Triangle pqr with vertices p(3, −6), q(6, −9), and r(−15, 3) is dilated by a scale factor of 3 to obtain triangle p′q′r′. which statement best describes triangle p′q′r′?
it is similar to triangle pqr and has coordinates p′(1, −2), q′(2, −3), and r′(−5, 1).
it is congruent to triangle pqr and has coordinates p′(1, −2), q′(2, −3), and r′(−5, 1).
it is similar to triangle pqr and has coordinates p′(9, −18), q′(18, −27), and r′(−45, 9).
it is congruent to triangle pqr and has coordinates p′(9, −18), q′(18, −27), and r′(−45, 9).
