Unit+1+Tri+Similarity

Two shapes are similar if they are the same shape, but just different size. This of it like this: same picture, different size. All the angles remain the same (look at the vertices on the cube. The edges increase proportionally. The sides of the cube are doubled so the side of the cylinder is also doubled. Once the scale factor is determined (the multiplier) can be applied to each side.
