Contour lines do not cross each other because of the variance in elevation between the lines. However, an instance where two contour lines intersect occurs when the elevations are simultaneously crossed at an identical point through a vertical ledge.
Know MoreContour lines are irregularly shaped patterns that typically form waves, concentric rings, loops or other oscillations that identify a meteorological quantity on a contour map. An "isobar" is associated with pressure, an "isotherm" with temperature, an "isotach" with the speed of wind and an "isodrosotherm" with dew point. The value of each atmospheric quantity is uniform along a contour line, hence, no two contour lines intersect.

Full Answer >Line symmetry of the alphabet occurs when a portion of a letter mirrors another portion. When the image is folded, the portions line up exactly. The line of the fold is considered the line of symmetry and can be horizontal or vertical.
Full Answer >Parallel lines are lines along the same plane that never intersect, even though they are of infinite length. If you are working on a construction project, it is important to make sure that segments that are supposed to be parallel actually are. To prove that two lines are parallel, you need a square or a protractor and a straight edge.
Full Answer >Perpendicular lines are those that form a right angle at the point at which they intersect. Parallel lines, though in the same plane, never intersect.
