It is called its perimeter.
A closed figure made up of line segments is called a polygon. The segments in a polygon are called sides or edges.
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.

Polygon.
If the line segments are straight, then it is a triangle.
a closed figure with all straight line segments is called a polygon.
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.

A closed figure made from line segments that meet at their endpoints is known as a polygon. Polygons can have various numbers of sides, such as triangles (3 sides), quadrilaterals (4 sides), and so on. The points where the line segments meet are called vertices, and the segments themselves are referred to as edges or sides. Polygons can be classified as regular (with equal sides and angles) or irregular (with varying side lengths and angles).
