You can use the theorems like SSS, SSA to show that they are similar. For example if two triangles have the same 3 sides length or two side lengths equal and 1 angle equal they are similar.

That is congruent, not similar! Similar is a weaker requirement. All that is needed is that two corresponding angles are the same. Equivalently, the three corresponding sides are in the same proportion.

What do you call two triangles with proportional sides?
They are said to be similar but not congruent triangles.
When will two right triangles be similar?
To prove that two right triangles are similar, all you need to show is that one of them has one acute angle that's equal to one acute angle of the other one.
What is the term used for the Triangles whose corresponding angles are equal?
They are similar triangles.
Two equilateral triangles are sometimes similar?

How do the ratios of side lenghts compare for triangles that are not similar?
There are no ratios that can be used for triangles that are not similar.
Is angle angle angle a way to show that triangles are similar?
Yes, AAA is a way to show that triangles are similar. Note, however, that AAA is not a way to show that triangles are congruent.
