Law of triangles

WebBased on these specifications and design, the properties of triangles are defined for all its different types. As the name suggests, a “triangle” is a three-sided polygon having three angles. The sum of all interior angles of a triangle will always add up to 180 degrees. This is called the angle sum property of triangle.
