Definition:Right Circular Cone/Similar Cones

Definition
Let $h_1$ and $h_2$ be the lengths of the axes of two right circular cones.

Let $d_1$ and $d_2$ be the lengths of the diameters of the bases of the two right circular cones.

Then the two right circular cones are similar {{{iff}}:


 * $\dfrac {h_1} {h_2} = \dfrac {d_1} {d_2}$
