  3. 4. A straight line segment whose endpoints both lie on the circle.
  4. 6. The total distance around the outside edge of a circle or any other round shape.
  5. 7. The area inside a circle that is enclosed by a chord (a straight line connecting two points on the circle) and an arc (the curved boundary between those two points).
  6. 9. A straight line cutting the circle at two points. It is also called an extended chord.
  7. 10. A line segment having both the endpoints on the circle and is the largest chord of the circle.
Down
  1. 1. This theorem states that the angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment.
  2. 2. A region bounded by two radii and an arc.
  3. 5. A straight line that touches the outer edge of the circle at exactly one single point.
  4. 8. A line segment connecting the centre of a circle to any point on the circle itself.
