Answer:

Because they're all have the same angles

Step-by-step explanation:

Triangles are similar to each other based on their angles.  Two similar triangles have the same angles (in the same order).

Since equilateral angles all have 3 angles of 60 degrees... they're all similar to each other.  The only variation is the length of their sides.

That's why you can't tell them apart!  One for all, all for one!
