How to check 2 triangles are similar ?

Qustion 1:
=======

suppose, you have been given 2 triangle , triangle ABC and triangle DEF.

How do i check that 2 triangles are similar ?

shoul i check corresponding angles ...whther they are same or not ? again the "corresponding" is a vauge word...because if i rotate a triangle, then the meaning of "corresponding" changes .

whats the proper way to check 2 triangles are similar ?

Question 2:
=========

suppose, there are 2 triangles ABC and DEF....ok.....now you you found that they are similar by some deterministic way ......now, say, you rotate the second triangle a little.

can we say again , that ABC and DEF are still similar ? YES/NO ?
and why ?

I've always thought that past civilizations that had experienced this transition in time had their DNA transformed and were able to use the rest of thier brains for psycho-kenetic abilities. Just a theory.
