Triangle A″B″C″ is formed using the translation (x + 0, y + 2) and the dilation by a scale factor of 2 from the origin. Which equation explains the relationship between segment AC and segment A double prime C double prime?

coordinate plane with triangle ABC at A negative 3 comma 3, B 1 comma negative 3, and C negative 3 comma negative 3

segment AC over segment A double prime C double prime = 2
segment A double prime C double prime over segment AC = one half
segment AC = segment A double prime C double prime over 2
segment A double prime C double prime = segment AC over 2

Answer 1

old question but will respond so this can be closed

going from AC to A"C" the triangle gets translated using the rule (x + 0, y + 2), as well as dilated by a factor of 2. the translation doesn't actually affect the side lengths of AC (translation is rigid). so, since AC gets dilated by a factor of 2, AC is half the length of A"C".
