It is bisected by line AC.

That's a transversal.

You're going straight.

Take the straight and narrow path

And maybe this will encourage people to get colonoscopies that wouldn't have otherwise.

And similarly, you can make the argument that this line segment right here is equal to is congruent to that line segment.

And then we have these transversals that go across them, so you have this transversal BC right over here and we have transversal AD

The length of segment AB must be the same as the length of segment DC, and both segments are horizontal segments.

This past year I've been in Latin America, I've been in China, talking about the fundamentals of laparoscopic surgery.
