#triangle properties

Triangles are a part of geometry in mathematics. A triangle has its own unique shape which makes it different from different geometrical shapes that we come across in our everyday lives. A triangle is actually a closed polygon having three straight sides and three angles. The sum of the angles of a triangle is always 180 degrees. The polygon can form only when the sum of the total of the internal angles are 180 degrees. This phenomenon can be referred to as the sum property of a triangle.
