What to Focus On

  • A straight line is also called a curve in mathematics.
  • An open curve does not cut itself.
  • A closed curve cuts itself.
  • A polygon must be closed.
  • A polygon is made only of straight-line segments.
  • Segments meet only at end-points.
  • Convex polygon: every angle is less than 180°.
  • Concave polygon: at least one angle is more than 180°.
  • Re-entrant polygon is another name for a concave polygon.

Common Mistakes to Avoid

A curve must be bent, so a straight line is not a curve.

An open curve is a curve that has open ends, and a closed curve is one that has no gaps.

Any closed curve is a simple closed curve.
