Point of interception.
Rotational symmetry.
There is no specific name for lines that meet at one point, but lines that meet at a point, the point is called the intersection point.
An angle is a pair of lines (actually rays) that share a common endpoint.Lines that share a point are said to be intersecting.The point at which the intersect is called the intersection point.Intersecting lines are lines that share a common point.
Two or more lines meeting at a common point are called intersecting lines.
a point
There are 66 lines. As no 3 points are co-linear, every line passes through exactly two of the points. Thus every point is joined by one of the lines to every other point. So it looks like there are 12 × 11 = 132 lines. However, the line joining point A to point B is the same as the line joining point B to point A; in other words, every line has been counted twice, once for one of the points it passes through and again by the other point it passes through. Therefore there are half the number of lines discovered above, name 132 ÷ 2 = 66 lines. This is the same as the "handshake problem" where everyone at a party shakes hands with everyone else at the party and the question is how many handshakes are there; the points are the people and the lines are the handshakes.
The name, if any, will depend on what lines are concurrent.
The origin
Yes, it is called the "Nezer Point".

longtitude and latitude are the lines used to pin point your location on the globe, are these the lines you are refering to?
I don't know ... it sounds kind of like what you have after you take off a really tight bra. How about Stay IN the Lines, or Stay ON the Lines?
