Triangle
A triangle is a geometric figure that is made of three line segments. It is a closed figure and has three angles.
This is the description of a triangle.
A geometric figure that has three line segments for sides is a triangle. Rectangles and squares are made of four line segments, while a circle is made out of a pair of arcs.
A polygon.
A closed figure made up of line segments is called a polygon. The segments in a polygon are called sides or edges.

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.
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.
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.
