A student asks if all cubes are similar and all spheres are similar. How do you respond?
A. Two figures are similar if they have the same shape and the same size. Therefore, all cubes are similar, but all spheres are not necessarily similar.
B. Two figures are similar if they have the same shape, but may be different in size. Therefore, all cubes are similar and all spheres are similar.
C. Two figures are similar if they have the same shape, but may be different in size. Therefore, all cubes are similar, but all spheres are not necessarily similar.
D. Two figures are similar if they have the same shape and the same size. Therefore, only cubes and spheres of the same size are similar.
