Interior Angle of the Given Pentagon:
IA = Interior Angles
NS = Number of Sides
IA = (NS - 2) × 180⁰÷ NS
= (5 - 2) × 180⁰ ÷ 5
= (3) × 180⁰÷ 5
= 540⁰ ÷ 5
= 18⁰
Interior Angles is = 18
Sum of All Interior Angles of Given Pentagon:
SA = Sum of All Interior Angles
NS = Number of Sides
SA = (NS - 2) × 180⁰
= (5-2) × 180⁰
= (3) × 180⁰
= 540⁰
Sum of all Interior Angles is = 540⁰
