Apart from the Bermuda Triangle there is also the Derbyshire Triangle in England and the Bonnybridge Triangle in Scotland.
I'm looking for any more you know of., and why triangles and not squares.

				Triangles are more efficient, that's why. 
			
			
			
				I've partially disappeared into some triangles.  :D

Triangle is the simplest 2D shape that has an area.
If you have a point on a plane, it's useful to mark that coffee shop you like or some such, but far too specific to group local events by.
Two points make a line. Nice for measuring distances, but "little" else.
Now, 
three points with lines between each one define an area within said lines. You can use additional points to tune the shape and resolution of said area, but for a first degree of approximation, you only need three.
It can be argued that an ellipsoid is an even simpler area-defining shape, but for the pies involved. Personally, I do appreciate a nice point and radius, as I can usually visualise the corresponding circle, but then that Origin may be quite arbitrary. For example, the Origin of the Bermuda 
circle may (and would) be in "no-place-of-interest, middle of the sea." Harder to visualise than the land masses of Florida, Puerto Rico and Bermuda with straight lines between them.
So yeah, what 
Recusant said.
			
 
			
			
				Not to be outdone on the tourist trail, Wales also has it's very own triangle.

But what is puzzling is that St. Brides Bay is more like a square than a triangle. 
Interesting that nearby on a headland a military base called RAF Brawdy was actually a tracking station for Russian submarines in the Irish Sea during the Cold War. 
"Is it possible" it was also a tracking station for aliens spacecraft as has been claimed.
			
			
			
				Saw a mention of the Lake Michigan triangle on Blaze TV.
It's worth considering that aliens are guided there by ley lines and they have bases at the bottom of the lake.
Like evidence for aquatic aliens as described in the Sirius Mystery by Robert Temple.
However I would like point out that the whole idea of lines of energy to guide visiting aliens is total bullshit.
According to Alfred Watkins from Hereford, ley lines are lines of energy which criss-cross most of England and Wales. 
This was described in his book The Old Straight Track.
They are supposed to be straight but they are not.
They intersect at major sites like Stonehenge and Avebury, but they don't.
They link up sites of other prehistoric significance like stones, burial mounds, wells and crosses, but they don't.

				Spoiler alert.
The "Indian Bermuda Triangle" is not a widely recognized or scientifically established term. The original Bermuda Triangle refers to a specific area in the North Atlantic Ocean where numerous ships and aircraft have mysteriously disappeared. There's no established equivalent area in Indian waters with similar claims of unexplained disappearances. The idea of dinosaurs in either the Bermuda Triangle or an "Indian Bermuda Triangle" is purely speculative and not supported by any scientific evidence. 
			
			
			
				Nearly ten times more people have disappeared in the Alaska Triangle than the Bermuda one.
Should we explain this by the terrain and wild animals or Bigfoot and alien abduction?
