They're not. A "great circle" is a circle drawn on a sphere that has its center at the center of the sphere. -- The only line of latitude that's a great circle is the equator. None of the others are. -- Each meridian of longitude is 1/2 of a great circle. In order to form a complete great circle, you have to glue it together with the other meridian of longitude that's directly opposite it on the other side of the globe. Like the Prime Meridian and 180° longitude, or 34° east longitude and 146° west longitude.

The Antarctic Circle is the collection of all the points on earth that are 23.5 degreessouth of the equator ... 23.5 degrees south latitude.
Lines of latitude stay where they are and do not run anywhere. Every one of them forms a complete circle around the world.

The Prime Meridian and the meridian of 180° longitude combine to forma great circle on the Earth. Each of them alone is a semi-circle.Every parallel of latitude also circles the Earth completely, but among those,only the equator is a great circle.
They are both imaginary lines which circle the earth!
