There are two ways to think of this question, if the triangles don't have to intersect then the answer is zero. If the triangles have to intersect, then the minimum number of points is one, if the triangles meat at vertex to edge or vertex to vertex.
When three or more lines intersect at one point, then they are considered concurrent.The four points of concurrence in triangles are the circumcenter, incenter, centroid, and orthocenter.
If two different lines intersect, they will always intersect at one point.
Point.
yes but they shouldn't run into eachother if they have there lights on
yes, three planes can intersect in one point.
If two circles intersect then they have to intersect at two points.
No, two straight lines can intersect at only one point and that is their point of intersection.
wrong!
No, they intersect at a line.
To intersect.
It's possible, but for any three lines in the same plane, there could be ether one point of intersection (unlikely) or three (more probably).
