Question

find the sum of thr interior angless (in degrees) of a polygon of

Answer 1

sum of interior angles= (n-2)×180

here n is number of sides
.

put values in formula..and get answers

Answer 2

(i) n = 4 sides

  sum of interior angles = (n-2) 180°

                                        = (4-2) 180°

                                        = 2 * 180°

                                        = 360°

by using the formula,

                                   (n-2) * 180°       ,  where n is the number of sides
