Sum of interior angles of the regular polygon.
Sn = ( n - 2 ) ∙ 180°
n is the number of sides
A heptagon has 7 sides so:
n = 7
S7= ( n - 2 ) ∙ 180° = ( 7 - 2 ) ∙ 180° = 5 ∙ 180°= 900°
Sn = ( n - 2 ) ∙ 180°
n is the number of sides
A heptagon has 7 sides so:
n = 7
S7= ( n - 2 ) ∙ 180° = ( 7 - 2 ) ∙ 180° = 5 ∙ 180°= 900°
