## Line

###
Line

`Line[`point A, point B`]`
  Line through two points A and B

`Line[`point A, line g`]`
  Line through A parallel to g

`Line[`point A, vector v`]`
  Line through A with direction v

###
Perpendicular

`Perpendicular[`point A, line g`]`

###
FirstAxis

`FirstAxis[`conic c`]`
  Principal axis of a conic section

###
SecondAxis

`SecondAxis[`conic c`]`
  Second axis of a conic section

###
Polar

`Polar[`point A, conic c`]`
