The alternate segment theorem states that the angle between a tangent and a chord through the point of contact is equal to:
AAngle in the alternate segment
BAngle at the center
C90 degrees
DAngle in the same segment
✓ Correct Answer: A — Angle in the alternate segment
This is a standard theorem in circle geometry relating tangent-chord angles to interior circle angles.
