'Sum of interior angles' for 8th grade
8th grade / Geometry & measures / Polygons / Interior and Exterior angles / Sum of interior angles
Polygons: calculate the sum of interior angles from the number of sides
Any polygon with more than 3 sides can be split into a series of triangles by drawing lines between corners. Since we know that the interior angles of triangles sum to 180°, we can calculate the sum of the interior angles of any polygon by multiplying the number of triangles it contains by 180°. A shorthand version of this calculation is to take 2 away from the number of sides of a polygon and multiply that number by 180°.
The formula for calculating the sum of interior angles of a polygon given the number of sides is:
Sum of interior angles = (N - 2) x 180°
(where N = Number of sides and 180° = sum of interior angles of a triangle)
So, for any polygon with 5 sides (pentagon), the interior angles sum to:
3 x 180° = 540°
For a polygon with 10 sides (decagon), the interior angles sum to:
8 x 180° = 1440°
For a polygon with 3 sides (triangle), the interior angles sum to:
1 x 180° = 180°
