A line is a figure that has no endpoints. It extends infinitely in both directions, characterized by having length but no width or thickness. In geometry, a line is often represented by a straight path that continues indefinitely, distinguishing it from line segments, which do have defined endpoints.

A semi-circle is a noun. It refers to a two-dimensional shape that represents half of a circle. In geometry, it is defined by a curved edge and a straight diameter. It does not function as a verb.
It is a very basic concept which cannot be defined. Undefined terms are used to define other concepts. In Euclidean geometry, for example, point, line and plane are not defined.
A circle is typically considered to have zero sides, as it is a continuous curve with no straight edges or vertices. In geometry, sides are defined as the straight line segments that form the boundaries of polygons, and since a circle does not fit this definition, it is classified as having no sides.
A straight line is often referred to simply as a "line" in geometry. It is defined as the shortest distance between two points and extends infinitely in both directions without any curvature. Mathematically, it can be represented using a linear equation in a coordinate system.
A point can be defined as a mathematically precise location.
In Euclidean geometry point, line and plane are not defined.
