दिलेल्याप्रमाणे

प्रत्येक आंतरकोन = 144°

वापरलेले सूत्र 

प्रत्येक आंतरकोन = 180(n - 2)/n   (n = बाजूंची संख्या)

गणना

प्रत्येक आंतरकोन = 144°

⇒ 180(n - 2) = 144n

⇒ n = 10

∴ बहुभुजाची बाजूंची संख्या 10 आहे.

प्रत्येक आंतरकोन = 144°

प्रत्येक बाह्यकोन = 180 - 144 = 36°

बाजूंची संख्या = 360/36 = 10

∴ बहुभुजाची बाजूंची संख्या 10 आहे.
