I need help knowing if 'two figures are similar. They are related by a scale factor of 1.'

a. the second figure is on size larger then the first figure
b. the second figure is one size smaller than the first figure
c. one figure is twice as big as the other
d. the two figure are congruent

I don't understand what the question is. Are you told that two figures are similar and related by a scale factor of 1 and asked which of the choices is true?

yes the two figures are similar and related by a scale factor of 1. i must choose one of those answers.

Isn't it obvious? Since the figures are similar they all have the same angles, and the scale factor is 1. Multiply each of the side lengths by 1 and what do you get?
