Parallel lines NEVER touch, so zero.
parallel lines never intersect.
Zero; they never intersect and therefore they do not have a solution.
The coordinate plane or grid.
Zero
Zero; parallel lines never intersect.
Depends on the lines. Anywhere from zero to infinitely many. If they are straight lines, then the answer is zero, one or infinity.

They are the x any y axes that are perpendicular to each other and intersect at zero on the Cartesian plane.
Parallel lines lying in a plane do not intersect each other. They share exactly zero points in common.
Any two lines can only have one point of intersection. Unless they are parallel, in which case they do not intersect at all. If they are the same line, then they intersect at an infinite number of points.
The Cartesian plane consist of an horizontal x axis number line and a vertical y axis number line and both axes are perpendicular to each other intersecting at the point of origin which is at (0, 0) or at their respective number lines which is zero.
Cartesian Or the origin
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.
