Why a triagle is always 180 degrees?

That is the angle sum of all three angles. This is a pattern in all polygons. Every time you add a side to a polygon, it's angle sum adds by "180". Since a two sided polygon is not possible, the tree sided triangle starts with 180 degrees. For example, an equilateral triangle will always have 60 degrees as the degrees for one edge, because 60 times 3 will equal 180. Quadrilaterals will have 360 degrees as an angle sum, and so on.
