A three-sided polygon is called a triangle. It consists of three straight sides and three angles, with the sum of the interior angles always equal to 180 degrees. Triangles can vary in shape, including equilateral (all sides equal), isosceles (two sides equal), and scalene (all sides of different lengths). The simplest form of a triangle is a closed figure with three vertices connected by straight lines.
