ABCD is a quadrilateral inscribed in a circle with centre O. If ∠COD = 120° and ∠BAC = 30°, the minimum possible value of ∠BCD is _____
Question
Solution 1
To solve this problem, we need to use the properties of a cyclic quadrilateral and the circle.
Step 1: In a circle, the angle subtended by an arc at the center is double the angle subtended by it at any point on the alternate segment. So, if ∠COD = 120°, then ∠CAB = 1/2 * ∠COD = 60°.
