दिले:

चौकोनाच्या कोनांचे गुणोत्तर = 2 ∶ 5 ∶ 7 ∶ 10

संकल्पना:

चतुर्भुजाच्या कोनांची बेरीज 360° आहे हे आपल्याला माहीत असल्याने, या गुणधर्माचा वापर करून चौकोनाच्या सर्व कोनांच्या मूल्यांची गणना करा.

गणना:

चला, कोन 2x, 5x, 7x, 10x असू द्या.

2x + 5x + 7x + 10x = 360°

⇒ 24x = 360°

⇒ x = \(360^\circ\over 24\)  

⇒ x = 15°

सर्वात मोठा कोन = 10x = 10 × 15° = 150°

सर्वात लहान कोन = 2x =2 × 15° = 30°

सर्वात लहान आणि सर्वात मोठ्या कोनामधील फरक = 150° - 30° = 120°

∴ '120°' हा सर्वात मोठा आणि सर्वात लहान कोनामधील फरक आहे.
