A polygon. A plane is two dimensional, like a coordinate plane or flat drawings on a piece of paper. If you drew three connecting line segments on a piece of paper, you would be left with a triangle. Four lines create a quadrilateral. Five lines could create a pentagon. All of these shapes are examples of polygons.

Yes, but a sector of a circle is also formed from three coplanar segments: two straight line segments and one curved. And it is very definitely NOT a polygon.
IF (and only if) the lines are al coplanar, then a polygon.
A polygon.

If rays, parallel ones. If segments there are many more options because you can have a segment that is not long enough to reach the point of intersection.
If the question required that the lines were straight, then they would be polygons, but since the question does not, there is nothing that can be said about the figures.

Polygon and they do not cross.
A simple closed figure formed by three or more segments is called a polygon. Regardless of how many sides a polygon has, all polygons will have as many vertices as it has sides.
Triangle: A figure formed by exactly three (non-colinear) points joined by line segments is a triangle. A figure formed by three or more points is generally called a polygon. Of course, if all of the points are co-linear then there is not much of a figure. A polygon has 3 or more sides.
