△ABC ~ △DEF means "triangle ABC is similar to triangle DEF."

If you take a triangle and multiply each of its sides by some number, you will get a similar triangle.

For example:

If you take △ABC and multiply each of its sides by 2, you will get △DEF. So △ABC ~ △DEF

( Also note that the order of the letters in the triangle name matters.

For example, in this case it is NOT true that △ABC ~ △FDE )
