# If a chord AB subtends an angle of 60° at the center of a circle, then angle between the tangents at A and B is also 60°.

False

Consider the problem in above diagram. In which we have a circle with center O and AB be any chord with AOB = 60°

Now,

OA AC and OB CB [ As tangent to at any point on the circle is perpendicular to the radius through point of contact]

OBC = OAC = 90° [1]

OBC + OAC + AOB + ACB = 360°

90° + 90° + 60° + ACB = 360°

ACB = 120° [2]

So the angle between two tangents is 120°. So the above statement is false .
