George is given two circles, Circle and circle X, as shown. If he wants to
prove that the two circles are similar, what would be the correct fourth step in
his proof?
Given: The radius of circle Oisr, and the radius of circle Xisr
Prove: Circle Ois similar to circle X
1.C - 2.1 and C - 2er' by the definition of circumference,
20
-- by the division property of equality.
3.d = 2r and d = 2r by the definition of diameter
by the substitution property
6. Circle Ois similar to circle X because all the linear dimensions are in the
same proportion
