  3. 6. a straight line segment whose endpoints both lie on the circle. A secant line, or just secant, is the infinite line extension of a chord. More generally, a chord is a line segment joining two points on any curve, for instance an ellipse.

  1. 1. of a sector: A "pie-slice" part of a circle - the area between two radiuses and the connecting arc of a circle.
  2. 3. plane figure enclosed by two radii of a circle or ellipse and the arc between them.
  3. 4. measure:In a circle, the length of an arc is a portion of the circumference.
  4. 5. of tangenA line which touches a circle or ellipse at just one point. Below, the blue line is a tangent to the circle c. Note the radius to the point of tangency is always perpendicular to the tangent line.cy:
