##
Arc and Sector

The algebraic value of an arc is its lenght, the value of a sector is its area.

###
Semicircle

`Semicircle[`point A, point B`]`
  Semicircle above the segment AB.

###
CircularArc

`CircularArc[`point M, point A, point B`]`
  Circular arc with midpoint M between two points A and B. Note: point B does not have to lie on the arc.

###
CircumcircularArc

`CircumcircularArc[`point, point, point`]`
  Circular arc through three points

###
Arc

`Arc[`conic c, point A, point B`]`
  Conic section arc between two points A and B on the conic section c (circle or ellipse)

`Arc[`conic c, number t1, number t2`]`
  Conic section arc between two parameter values t1 and t2 for the following parameter forms:
  - circle: (r cos(t), r sin(t)), where r is the circle's radius
  - ellipse: (a cos(t), b sin(t)), where a and b are the lengths of the first and second axis

###
CircularSector

`CircularSector[`point M, point A, point B`]`
  Circular sector with midpoint M between two points A and B. Note: point B does not have to lie on the arc.

###
CircumcircularSector

`CircumcircularSector[`point, point, point`]`
  Circular sector through three points

###
Sector

`Sector[`conic c, point A, point B`]`
  Conic section sector between two points A and B on the conic section c (circle or ellipse)

`Sector[`conic c, number t1, number t2`]`
  Conic section sector between two parameter values t1 and t2 for the following parameter forms:
  - circle: (r cos(t), r sin(t)), where r is the circle's radius
  - ellipse: (a cos(t), b sin(t)), where a and b are the lengths of the first and second axis
