Alternate Segment Theorem Flashcards

The angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment.

A straight line that touches a circle at exactly one point.

A straight line joining two points on the circumference of a circle.

The point where a tangent touches the circle.

The region of the circle opposite to the angle formed by the tangent and chord.

The angle between the tangent and chord equals the angle in the opposite segment of the circle.

Used to find unknown angles in problems involving tangents and circles.

A tangent, a chord, and angles in the alternate segment must be present.

Not required for GCSE; focus is on understanding and applying the theorem.

Confusing the angle in the alternate segment with angles in the same segment.
