Black triangle (UFO)
So there are some people who say they have seen a black triangle in the sky that they think is a UFO. A UFO stands for Unidentified Flying Object, which means they don't know what it is or where it came from.
Now, when they say "black triangle," they mean a shape in the sky that looks like a triangle but it's all black. They say it doesn't have any lights or windows like a plane or helicopter.
Some people think that the black triangle might be a secret aircraft that the government is testing. Others think it might be aliens from another planet visiting us.
But, no one really knows for sure what the black triangle is or if it even exists. So it's still a mystery that people are curious about.
