सिद्ध किया की चक्रीय समांतर चतुर्भुज एक आयत होता है।
Step-by-step explanation:
सिद्ध करना है की
चक्रीय समांतर चतुर्भुज एक आयत होता है
माना ABCD चक्रीय समांतर चतुर्भुज है
ABCD समांतर चतुर्भुज
=> AB = CD & BC = AD
∠A = ∠C & ∠B = ∠D
ABCD चक्रीय चतुर्भुज
=> ∠A + ∠C = 180° & ∠B + ∠D = 180°
∠A = ∠C
∠A + ∠C = 180°
=> ∠A = ∠C = 90°
∠B = ∠D
∠B + ∠D = 180°
=> ∠B = ∠D = 90°
AB = CD & BC = AD ∠A = ∠B = ∠C = ∠D = 90°
=> ABCD आयत है
