Question was what was the best way to join the chanel at right angles (considering look and weatherprrofing etc.)?

As per attached should I cut at 45 and join sealing with sealant etc.? Or try and slot one into the other and then seal?

TIA

I would be slotting the side one under the back one and notch the side one underneath only if necessary and silcone in the corner to stop the ingress of water.
