Yes.
A circle is not formed from line segments.
A closed plane figure formed by three or more line segments that do not cross is called a polygon. The line segments are known as the sides of the polygon, and the points where the sides meet are called vertices. Common examples of polygons include triangles, quadrilaterals, pentagons, and hexagons. Polygons can be classified as regular, with equal sides and angles, or irregular, with varying lengths and angles.
Plain shapes are typically defined by their line segments and angles. A polygon, for instance, is a plain shape consisting of a finite number of line segments (sides) connected end-to-end, forming a closed figure. The number of angles in a polygon corresponds to the number of sides, with each vertex where two sides meet forming an angle. For example, a triangle has three line segments and three angles, while a square has four line segments and four angles.
If it has 3 or more line segments then it is a polygon
a pentagon has five sides and five angles
When two line segments meet at a point
what of a triangle has three line segments that intersect only at their endpoints
A circle is not formed from line segments.
An angle comprises two straight line segments or rays together with the point at which they meet.
Perpendicular line segments are line segments that cross with each other and form angles of 90 degrees.
Perpendicular line segments are line segments that intersect and make 90 degree angles.
You cannot have a shape without any line segments.

A simple closed figure formed by line segments joined together. The point where the sides meet is called the vertex (vertices, plural). A regular polygon is formed when all the sides are equal. Polygons are named by the number of sides and angles they contain.
If it has 3 or more line segments then it is a polygon
The definition of perpendicular lines also defines the angles -- perpendicular lines are two lines (or line segments) that meet at a 90 degree angle.
