what is n 2 x 180 The sum of all interior angles of a regular polygon is calculated by the formula S n 2 180 where n is the number of sides of a polygon For example to find the sum of interior angles of a pentagon we will substitute the value of n in the formula S n 2 180 in this case n 5
A short video showing how to prove the sum of the angles in a n sided polygon is 180 n 2 For example a hexagon has 6 sides so n 2 is 4 and the internal angles add up to 180 4 Use the formula 2 180 where is the number of sides of the polygon which gives 5 2 180 3 180 540 The sum of the interior angles in a pentagon is 540

The number of triangles formed by connecting the vertices of a polygon will always be 2 less than the number of sides n Therefore we have sum of interior angles of a polygon is n 2 180 where n is the number of sides Answer n 2 180 formula is used to find the total sum of the interior angles of a regular polygon
The sum of all the angles in all the triangles equals the sum of the interior angles of the polygon Notice that the shape has 7 7 sides and we are able to fit 5 5 triangles inside it each of whose angles sum to 180 180 degrees This generalises to a n n sided polygon being able to fit n 2 n 2 triangles inside it as shown above Method 1 From any one of the vertices say A1 construct diagonals to other vertices There are altogether n 2 triangles Sum of angles of each triangle 180 Sum of interior angles of n sided polygon n 2 x 180 Method 2 From any point P on the line segment say A1 A2 construct lines to the vertices A3 A4 An
