Types Of Spiderwebs
Background
While not all spiders construct webs, they all use silk in one way or another. They also have different kinds of silk for different things!
Spiral/Orb Webs
Most people will only think of one specific structure when referring to webs. That is the Orb web, otherwise called the spiral web. These kinds of webs are usually built by garden spiders and such. They are symmetrical, wheel-shaped and the most popular web used in spider media, whether that be films, comics, or some other form of media.
Sheet webs
Sheet webs are horizontal layers of silk, only having fine vertical threads to knock the web down if needed. The size of a sheet web depends on the size of the spider that wove it, because these spiders usually wait under their web at night, biting through the silk once they sense something there. In the daytime however, they have a tunnel to retreat in.
Tangle webs

Triangle webs
These webs look like a slice of pizza, and unlike other webs, aren't sticky. Instead, they have little fibers that give them fuzz, which helps ambush prey. One spider even turns this web into a slingshot, pulling on the silk and propelling itself and it's web forward enough times for the silk strands to fall and trap it's prey!
Funnel webs
Flat horizontal webs that have a tube leading to the spider's burrow. The spiders that make these wait inside their home, waiting for their dinner to enter the parlour. These are usually tucked between rocks or plants and have a really good backdoor for escaping danger as a spider. To not confuse them with sheet webs, look for vertical strands that seem to be for knocking down.
