Question

write the formula for sum of interior angles of N sided polygon using the formula write the sum of interior angle of an octagon

Answer 1

Sum of interior angles of N-sided polygon is ( n - 2 ) x 180.

An octagon has 8 sides

Sum of interior angles = ( 8 - 2 ) x 180 = 1080°

Answer: Sum of the interior angles on an octagon is 1080°

Answer 2

Here is your Answer

Let the Number of Sides be N

Formula (For Regular Polygons)=

(n-2) × 180

Sum of Interior Angles of Octagon = (8-2) × 180

= 6 × 180

= 1080
