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 fourth step in
his proof?
given: the radius of circle oisr, and the radius of circle x is l'.
prove: circle ois similar to circle x.
1.c - 2x and c - 2xy' by the definition of circumference.
c-2
by the division property of equality.
3. d = 2r and d = 2' 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
