In fig 3 angle acb 90

WebAOB is a diameter of the circle AC = BC We know, the diameter subtends a right angle to any point on the circle. ∴ ∠ACB = 90° ... (1) In ∆ACB, AC = BC (given) ∴ ∠CAB = ∠CBA (angles opposite to equal sides are equal) ... (2) Now, ∠CAB + ∠CBA + ∠ACB = 180° (angle sum property) ⇒ 2∠CAB + 90° = 180° (From (1) and (2)) ⇒ 2∠CAB = 180° − 90° ⇒ 2∠CAB = 90° WebThus in triangle ABC we have , AB² + AC²= BC² hence triangle ABC is a right triangle right angled at A ∠ BAC = 90° Second Method:- AD^2 = BD × CD AD ÷ CD = BD ÷ AD ΔADC ∼ ΔBDA (by SAS ∠D = 90°) ∠BAD = ∠ACD ; ∠DAC = ∠DBA (Corresponding angles of similar triangles) ∠BAD+ ∠ACD + ∠DAC + ∠DBA = 180° ⇒ 2∠BAD + 2∠DAC = 180° ⇒ ∠BAD + ∠DAC = 90° ∴ …
