Concurrent Parametrizations












0












$begingroup$


I'm currently working on a problem. I have found the parametrizations of 5 lines using position vectors, so in the form of $overrightarrow{Q} = (1-s) overrightarrow{B} + s overrightarrow{T}.$



How would I go about proving that these parametric lines are concurrent? I have them graphed in GeoGebra, and they are. In addition, how would I find the point of concurrency?



Thank you!

    One way: pick one, represent is as the intersection of two planes and then show that the rest of the parameterizations satisfy the two equations.
