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° WebClick here👆to get an answer to your question ️ \"5.
