A triangle? Three lines that intersect in three points.
What is a noncoplanar its not parallel and do not intersect?
In space with 3 or more dimensions, there are infinitely many pairs of lines that are not parallel and do not intersect.
What lines intersect at -2 3?
There is an infinite number of lines.
When 3 or more lines intersect in a point they are said to be what?
Concurrent lines
How many intersects are there for 4 lines?
Maximum 12 intersections are there! You can simply use the formula: No. of intersections = n(n-1)/2 [where 'n' is the number of lines] This is derived as each new line can intersect (at most) all the previously drawn lines. There if there is: 1 line => 0 intersections 2 lines => 1 intersection 3 lines => 3 intersections [1 that was there + 2 by the new line can intersect both the previous lines.] 4 lines => 6 intersections [3 that were already there + 3 because the new line can intersect all the 3 lines that were present previously.]
