For some reason, I cannot find the list of triangle side ratios on Google…

I know that 30-60-90 triangles have a ratio: 3-4-5

I would really appreciate it if you can let me know of others for the 30-60-90 and 60-60-60 triangles! Also, would it be correct to call them triangle side ratios?

In addition, I’ve been feeling that I should memorize all of them. Is this actually necessary?

Not all 30-60-90 triangles have side ratio of 3-4-5, it is one of the many pythagorean triplets. You dont have to memorize them, but if you do it does save some time.
