I think it's called a contigous region, or maybe a bounded area, something like that.
A Maze

a line segment
straight line
actually, there is, depending on your definition of polygon, and your definition of a line segment. A line segment is the shortest path btwn two points, right? So take a sphere and pick any two points on that sphere. The shortest path between them on the surface of the sphere would be a "curve" along the surface, but it's the shortest path between the points, so it technally is a line segment. Take two of these line segments that intersect at two points, and there is your two sided polygon!
A Maze
short or short circuit
Circle.
That path might be called a circuit. If the path is complete, it's a closed circuit.
The path of Earth's orbit in the shape of an elongated closed curve is called an ellipse. An ellipse is a type of geometric shape that resembles an elongated circle, with two focal points inside the curve. This shape is a result of the gravitational forces between Earth and the Sun.
That is called orbital motion. it is the closed path that one object in space follows around another object, typically due to the force of gravity.
A closed path through which a current can flow is called a circuit. Electric Circuit:)
That is called a switch.
That's called the "distance" between the points.
Traveling in a closed path means that you start and end at the same point without leaving the path. In other words, you move in a loop or circuit, returning to your initial position after completing the journey.
To orbit the object.
That would be called a 'circuit' or 'closed circuit'.
