How are congruent triangles relevant to a suspension bridge? Where are the congruent triangles in this bridge picture?

Sorry if this is a stupid question, but I can’t find anything useful about this. Thanks.

edit: ok, this is for my geometry project. I just don't get how the congruent triangles help support the bridge.

Why do you want to know? Can you update this with your motivation for inquiring?

There are congruent triangles on the left and right sides of the bridge. There are also almost-congruent triangles all along the length of the bridge, when you consider adjacent triangles.

I can't say for sure, but I would say the significance of congruent triangles (as opposed to random triangles) is the fact that they can take similar amounts of force/stress, whereas different sized triangles would vary in the amount of force they could take, potentially creating weak points.

Triangles are of course the strongest shape.

Basically because triangles are structurally very strong.

Kinda basic and there's certainly a lot more math behind it but you get the idea.

That's along the lines of what I was thinking, but the only actual application I can think of is to properly choose the positioning of the towers to create congruent triangles on each end.
