concurrencyCondition
fun <C> PlanimetricsCalculationContext<C, *>.concurrencyCondition(l: Line<C>, m: Line<C>, n: Line<C>): LabeledPolynomial<C>
Returns an expression which equality to zero is equivalent to concurrency of the lines.
Obviously, it's determinant of matrix constructed by row vectors of the lines.
Return
The expression.
Parameters
l
The first line.
m
The second line.
n
The third line.
