In geometry, a triangle is a closed, two-dimensional shape with three straight sides. A triangle is also a polygon. A triangle has three sides, three vertices, and three angle. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side. The area of a triangle is equal to half of the product of its base and height. An acute triangle has all interior angles acute (less than 90°), a right triangle has one right angle (equal to 90°) and an obtuse triangle has one obtuse angle (greater than 90°). A triangle can always be split into two right triangles, irrespective of its orientation.Triangles are polygons with the least number of sides.
