Circumpolar, like beauty, is in the eye of the beholder. Technically, a circumpolar constellation is one that never sets, but just goes around the elevated pole. That's the north star Polaris in the northern hemisphere, or the blank spot of space above the south pole. This, however, depends on your latitude; the higher your latitude, the more constellations are "circumpolar" for you.
I live near Sacramento, CA, USA, at latitude about 38 degrees north, so any constellation within 38 degrees of Polaris is "circumpolar" for me. That includes constellations such as Ursa Major, Cassiopeia, and Draco, but not constellations like Orion.
All of them - except the ones that are circumpolar (that don't rise or set at all). Which ones are circumpolar depends on your latitude.
One: Draco. If you feel exceptionally generous you might also count Hydra, which represents a slightly different but somewhat dragon-like mythological creature.
Northern circumpolar constellations revolve around the north celestial pole in a counterclockwise manner. They never seem to rise or set, in regards to the horizon. Every 24 hours they seem to complete a revolution around Polaris, the North Star. Because the Earth is a sphere, the number of circumpolar constellations that one sees depends on one's location from the North Pole. At the North Pole, every constellation in the night sky is circumpolar. Below the equator, one cannot see a single circumpolar constellation. These are the common circumpolar constellations of 40-50 degrees N latitude: Ursa Major Ursa Minor Cassiopeia Cepheus Draco

No there are no circumpolar constellations on the equator.
"Circumpolar" means it is always above the horizon.
because the circumpolar constellations are visible all year long and the others are not.
The constellation Cassiopeia is a 'M' shape.

Circumpolar constellations means that a constellation orbits around the north star. Otherwise, polaris.
Cygnus is a constellation not quite circumpolar. It is visible from June to October. One of the best observing times for this constellation is in September at 9:00 PM.
gemini is not circumpolar. the circumpolar constellations for the northern hemisphere are Cassiopeia. Ursa Minor, Draco, Cepheus, and Ursa Major.

There are about 29 major constellations in the northern hemisphere. Of these, Cassiopeia has a rough M shape and is circumpolar.
Octans (the octant).
Circumpolar constellations are those that, from the viewer's latitude, never set. Any constellation found in the zodiac is not circumpolar. These are seasonal. Pisces appears in the Spring in the Southern hemisphere and in Autumn in the Northern hemisphere.
