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.

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. | ||

http://www.rogersconnection.com/triangles/index.html Kinda basic and there's certainly a lot more math behind it but you get the idea. | ||

There are also almost-congruent triangles all along the length of the bridge, when you consider adjacent triangles.

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. | ||
