Two ratios are equivalent if you can multiply each of the numbers in the first ratio by the same factor to get the numbers in the second ratio.
Figures that have the same shape but not necessarily the same size. Two figures are similar if one can fit exactly over the other after rigid transformations and dilations.
When part of an original figure matches up with part of a copy, we call them corresponding parts. These could be points, segments, angles, or distances.
