The amazon river is probably a trellis because it has 2 types of alternating soft and hard rocks. A trellis drainage is the rectangular drainage pattern created if rivers flow through alternating bands of hard and soft rocks.
The Amazon River is an example of dendritic drainage, which resembles the branching pattern of tree roots. Dendritic drainage patterns are common in areas with uniform rock structure and slope, where rivers and streams flow in multiple directions.

It is Dendritic
The nile is trellis
I would say Trellis because it doesn't look dendritic, but I can't be sure.
i'm not sure. I think it's a dendritic pattern
both
I don't know about 'treillis' rivers, but the Loire river seems to me to be dendritic (in the sense of arborescent)
The Amur River features dendritic drainage. This pattern of river system resembles the branching of tree roots and is common in areas with homogenous rock structures, where water flows in a branching pattern towards lower elevations.
trellis as the tributaries meet at approximately right angles
The Mississippi river is a dedentric drainage
Dendritic because the rivers cross a gradual slope over one basic type of rock.
