They're using them in the NHL now. Behind the net, there's two lines
that define the trapezoid. Four sides, plus one big downside: If a
goaltender plays the puck behind the icing line and outside the trapezoid
it's a minor penalty.
What it has to do with joist hangers, I don't know...

And if you have an iPad or iPhone Simpson has a free app listing their

I'm guessing a square or rectangle with one corner cut at an angle.

LOL I think geometry is a bit past counting. ;~) 5 sides vs. 6 sides

A moment's insight is sometimes worth
a life's experience.
Take from an old house framer...
Simpson makes fantastic framing and structural aids; the piece shown in the=
video and its application are unsuitable for a weight bearing member. Pro=
bably fine for a light weight roof structure application, but as a former F=
HA inspector, I certainly wouldn't pass it as a floor joist.
First, the cut on the joist should be a cheek cut so that when installed th=
e face of the joist is in 100% contact with the adjacent beam. Think of a =
roof joist in a hand framed roof and what the rafters look like when nailed=
to the hip joist. A long, angled "cheek" is cut on the rafter, then it is=
nailed to the hip rafter through the cheek.
Second, when I build a deck (or an odd second story on a house) and it has =
that kind of detail (compound angle cheek cut) I do as Mr. Ross observed, a=
nd install a ledger board. Properly nailed to your weight bearing beam, th=
ey will hold a tremendous load. So, cut the joist with a cheek cut and sim=
ply set it on ledger. If the bearing point is open more than 1/8", bevel t=
he entire ledger the appropriate angle for bearing, then attach. Or you ca=
n notch the bottom or the rafter (my preference) with the correct angles fo=
r 100% bearing.
After the proper cheek cut, you can use the Simspon tie on a deck and it sh=
ould work fine with the proper framing web work as part of the structure. =
=20
I think it is important to note that the Simpson video only shows the insta=
llation of their product, NOT suitability of purpose or recommendations for=
proper framing techniques. Note that the metal hanger is shown on its att=
achment on one side ONLY. If you are framing a weight bearing floor/deck a=
nd it slopes, for proper framing the joists should buttress to a heavy, non=
flexing beam as the angle has transferred not only the dead load, but the =
live load (and flex) to the lower end of the angle on the structure. Also,=
with the heavier beam (to negate LATERAL flex)in place on the low side, yo=
u have effectively "trapped" the joist on place.
I would highly recommend using/borrowing/buying a copy of Rob Thallon's "Gr=
aphic Guide to Frame Construction". Having framed a couple of hundred hous=
es from top to bottom, and then 40 years of remodel, repair, rebuilds, and =
modifications to different structures, I thought I had seen it all. Nope. =
I still use that book from time to time for details. It is the best I have=
ever seen on all matters framing. More importantly, no methods or details=
I have used in that book have ever failed or even been unsatisfactory.

The Simpson code is LSSU

There are, and yes, Simpson Strong Tie
Has them. Also, there is a lot of surface area for nail, screw our lag
attachment.
Some use pressure blocking also, in lieu of joist hangers, although in a wet
location, they tend to trap moisture over time, and can cause rot.
Some joist hangers come with an ability to free-scew......I know that sounds
a bit odd.....

A trapazoid with 5 sides(?). Don't go confusing this matter with
explanations that trapazoids only have 4 sides. I'm doing my best to keep
up...

So,mathematically,
a 5-sided trapezoid = parallelogram - triangle.

Well, leaving aside the "5-sided Trapezoid" bit, a parallelogram minus
a triangle could yield a triangle, a trapezoid (4 sided, naturally) a
pentagon (irregular) or a six-sided figure with a concave section. :)

The old house where I grew up was built in about 1920. They did not
have hangers, but a ledge was nailed on and the joists were cut out to
sit on the ledge then toenailed or through nailed.
