# What is a perfect triangle?

Update:

A man said he saw 3 lights in the sky (supposedly a UFO). He also said that these 3 lights formed a perfect triangle. But what is a perfect triangle?

Update 2:

I suppose that this man didn't know what is a perfect triangle.

Probably he meant it was an equilateral triangle

If you are describing three objects as ''forming a perfect triangle'' that would be an equilateral triangle.

If you think about it (unless they are in a straight line) three objects are always going to form some kind of triangle.
