Through a point K in the plane of a triangle Δ A B C, draw parallelians through a point as illustrated above. Then there exist four points K for which P_(A C) P_(C A) = P_(A B) P_(B A) = P_(B C) P_(C B), i.e., for which the segments of the parallels have equal length. To restrict these four points, let the length of P_(B C) P_(C B) be considered negative if P_(B C) lies on the extension of A B beyond A and P_(C B) lies on the extension of C A beyond A, and positive otherwise. Define the lengths of the other two parallelians to be signed in the analogous manner. With this sign convention, there is a unique point K for which the signed parallelians have equal length. This point is called the equal parallelians point of Δ A B C.

Club Z! has connected me with a tutor through their online platform! This was exactly the one-on-one attention I needed for my math exam. I was very pleased with the sessions and ClubZ’s online tutoring interface.
My son was suffering from low confidence in his educational abilities. I was in need of help and quick. Club Z! assigned Charlotte (our tutor) and we love her! My son’s grades went from D’s to A’s and B’s.
I’ve been using Club Z’s online classrooms to receive some help and tutoring for 2 of my college classes. I must say that I am very impressed by the functionality and ease of use of their online App. Working online with my tutor has been a piece of cake. Thanks Z.
Jonathan is doing really well in all of his classes this semester, 5 A’s & 2 B’s (he has a computer essentials class instead of PLC). In his Algebra class that Nathan is helping him with he has an A+.
Sarah is very positive, enthusiastic and encourages my daughter to do better each time she comes. My daughter’s grade has improved, we are very grateful for Sarah and that she is tutoring our daughter. Way to go ClubZ!
