Question

prove that the angle between the tangents and chord at the point of contact is equal to an angle of the alternate segment​

Answer 1

Answer:

The alternate segment theorem (also known as the tangent-chord theorem) states that in any circle, the angle between a chord and a tangent through one of the end points of the chord is equal to the angle in the alternate segment. In the above diagram, the angles of the same color are equal to each other.
