Question

ΔABC was dilated from the origin by a scale factor of 2 to create ΔA′B′C′. Which statement explains why the triangles are similar?

Dilations preserve side length; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve betweenness of points; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve orientation; therefore, the corresponding angles of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve angle measure; therefore the corresponding angles of ΔABC and ΔA′B′C′ are congruent.

Answer 1

what do you think the answer is

Answer 2

i think it is C

Answer 3

close but no

Answer 4

any other guess

Answer 5

it was between b and c so is it b?

Answer 6

Why do you think that

Answer 7

because when it is dilated it doesn't stay the same length and the angles don't stay the same
