Depends.
Bicycles with external gears have chain-and-sprocket gears.
Bicycles with internally geared hubs have both a chain-and-sprocket gear and spur gears (usually in a planetary configuration) inside the rear hub.
Then there are the rather rare shaft-drive bicycles, which use bevel gears. And maybe an internally geared hub as well. Then there's the occasional belt drive bike of course. And one or two CVT designs.
Planetary gears can be spur or helical gears.
Spur gears give 180 degree drive, and worm gears give 90 degree drive.
Spur Gears.
Spur gears have straight teeth while helical gears have curved teeth. Generally, helical gears are usually quieter and smoother in operation, while spur gears are easier to make and much less expensive.Helical gears are stronger than spur gears.
One of the most common types of gears is the Spur Gear. They are most round with teeth along the edging. Spur Gears are used in oscillating sprinklers or fans, windup clocks, washing machines and dyers.
There are three main types of gear combinations used in mechanical systems: spur gears, helical gears, and bevel gears. Spur gears have straight teeth and are used for simple applications. Helical gears have angled teeth for smoother operation and higher loads. Bevel gears have cone-shaped teeth and are used to change the direction of rotation.

No, they would need to be bevel gears. Peg gear wheels would but they are generaly made from wood and used for agriculture etc.
A haploid bevel gear has the advantage of lower friction and smoother operation compared to traditional spur gears. This design reduces wear and noise, making it ideal for applications requiring precision and efficiency.
The gear wheel used in tractors is commonly referred to as a "gear" or "gear set." These gears are part of the transmission system, which transmits power from the engine to the wheels, allowing the tractor to move and perform various tasks. Specific types of gears in tractors include pinion gears, spur gears, and bevel gears, each serving different functions in the drivetrain.
bevel gears are used for power transmitting between the shafts which intersect at some angel ( usually right angel) , but the spur gear is used for shafts which are parallel and coplanar.

It is called a gear tooth. There can be many types of teeth based on the gear design; such as spur, helical, straight bevel, spiral bevel, hypoid, and several others.
