---------------------
That's true. If you look at a 2-dimensional projection of a cone, it's a triangle, and increasing it by the same ratio makes them similar.

In solid figures, if linear dims are proportional, figures are similar.
.
Scale factor by radius are,,4/8 = 1/2,,,by height,,10/20 =1/2,,,,
.
Therefore they are similar
