Clearly designed to shield people from sun and rain.* But isn't
rectangular more sensible?* Triangles have those narrow corners in
three
places where they shield virtually nothing.

Wind resistance?* They have to survive in bad weather.

How does that help with wind?* My neighbour just put one up and it's
flapping about the same as a rectangular one would.* In fact I'd say the
more anchor points, the sturdier it is, a professional large one with
about 12 anchor points stays still in the highest winds.* And if it
doesn't actually shield much, might as well not have it at all.

One less pole :-)

What pole?* You can tie two corners to a shed or house, and the other(s)
to a tree or fence etc.* Don't tell me you have a house with no shed or
fence and only one tree?

No trees at all. South facing wall would provide the anchor point for
two points of the triangle, and a pole and guy cord would be needed
for the third corner.

Only Australians seem to have a collection of eucalyptus trees
around their houses.
