Total angle of polygon with n sides
WebThe total sum of interior angles of a polygon might be related to its number of sides by the following formula: [tex]S=(n-2)\times180[/tex] Here, S is the total sum and n is the number of sides. Therefore, the number of sides can be calculated as, [tex]n=\frac{S}{180}+2[/tex] Substituting for S, we get, [tex]n=\frac{1440}{180}+2=8+2=10[/tex ...

The angle sum of this polygon for interior angles can be determined on multiplying the number of triangles by 180°. After examining, we can see that the number of triangles is two less than the number of sides, always. Hence, we can say now, if a convex polygon has n sides, then the sum of its interior angle is … See more An exterior angle of a polygon is made by extending only one of its sides, in the outward direction. The angle next to an interior angle, formed by extending the … See more Question 1: Find the sum of interior angles of a regular pentagon. Solution: A pentagon has five sides. Therefore, by the angle sum formula we know; S = ( n − 2) × … See more WebJan 11, 2024 · It is a polygon that has n sides and n corners. The sum of the internal angle is 180 ( n - 2) degrees. 180 (n-2) = Total angle. The sum of the angle measures of a polygon with n sides is 1080, then. 180 (n-2) = 1080. n- 2 = 6. n = 8. Thus the number of sides of the polygon is 8. More about the polygon link is given below.
