Sum of interior angles of a triangle is _________

The general formula for the sum total of all the interior angles that are formed of any polygon is $(n-2)180°$

As we know, the sum of all the interior angles of any triangle is$180°$.

So, by using the above formula, Sum of interior angles=$(n-2)180°$.

Any triangles have three sides so $n=3$.

∴ Sum of interior angles$=(3-2)180°$

∴ Sum of interior angles$=180°$
