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 second step
in his proof?
given: the radius of circle oisr, and the radius of circle xis /'.
prove: circle ois similar to circle x.
1.c - 21 and c - 2xy' by the definition of circumference.
3. d = 2r and d = 2r by the definition of diameter.
4. = 27, and
by the division property of equality.
5.
-27, and --
by the substitution property.
6. circle ois similar to circle x because all the linear dimensions are in the
same proportion
