Two distinct lines can either intersect, be parallel or be skew. Curves whose interior zones do not intersect represent disjoint sets. These two narrative strands never quite intersect, though they do run in parallel. The diagonals of an "n"-parallelotope intersect at one point and are bisected by this point. The partition is then noncrossing if and only if these polygons do not intersect. Hypoid gears resemble spiral bevel gears except the shaft axes do not intersect. Manifolds that do not intersect are vacuously transverse. If the parabola does not intersect the -axis, there are two complex conjugate roots. But at the same time, more spheres will not generally intersect at one point. A simple polygon is one which does not intersect itself. The two circles will intersect in two points. Triple points are points on phase diagrams where lines of equilibrium intersect. Antananarivo encompasses three ridges that intersect at their highest point. These curves typically intersect at some altitude. There are two federal highways that intersect Manaus.
