Imagine two 900 triangles back to back with their bases horizontal making a straight line.
The bases are half of the bridge; one of the two sides is supporting the weight of the bridge the other is anchored to a solid point. The weight of the bridge is pulling the apexes of the two back to back triangles downwards; these two vertical sides of the triangles are the supporting column at one end of the bridge. Now imagine a mirror image of what I have described and you will see a suspension bridge.

the first Truss bridge was built by Palmer in 1811 in Philidelphia
you can check this out link below- its about Truss Bridges
Wilson Pratt Truss Bridge was created in 1904.
Yes
A truss bridge uses trusses as the load bearing element of the bridge. Using statics physics, a truss bridge applies Newtonian motion to ensure that the load bearing elements do not go out of a tension/compression equilibrium.
A truss is a diagonal brace which provides structural support for a bridge span by extending between a vertical member and the bridge span.
I want to build a truss bridge because truss bridge is most economical and his dead load is too low.
not truss
There are many forces acting on a truss bridge compression, tension, and torsion. The truss bridge uses equilateral triangles to spread out the stress of the load on these forces along the hold structure.
Simply put, a truss bridge is just a bridge built by trusses. Trusses are structural frames composed of triangular pieces/joints. So basically a truss bridge is just many triangular structural frames as a support for the bridge.
Truss
because of the support of the circles

truss
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
