George is given two circles, Circle O and circle X, as shown. If he wants to prove that the two circles are similar, what would be the correct first step in his proof?

Given: The radius of circle O is r, and the radius of circle X is r'.

Prove: Circle O is similar to circle X.

1. and by the definition of circumference.

2. and by the division property of equality.

3. d = 2r and d' = 2r' by the definition of diameter.

4. and by the division property of equality.

5. and by the substitution property.

hint: since you are given r and r' your first step would be to calculate another quantity (I can't say without giving away the answer) using r and r'
