We can very easily calculate the sum of the internal angles of a polygon using the following formula:
When: number of edges or sides of the polygon
In reality, the sum of all the internal angles of a polygon depends on the number of edges it has.
Steps to follow to find the sum of the internal angles of a polygon:
- Count how many sides it has.
- Place it in the formula and we will obtain the sum of the internal angles of the polygon.
In the formula, there are parentheses that require us to first perform the operations of subtraction (first we will subtract from the number of edges and only then multiply by .)
Regardless of the polygon you have, concave, convex, or regular, thanks to this formula you will be able to find the sum of the internal angles of any polygon.
