Looper lines or also known as "roping" in aluminum is a form of "surface roughening" which occurs during deep drawing or drawing and ironing operations. The origin of looper lines occur during ingot casting, homogenization and rolling practices. The coarse grain structure are formed during the hot rolling or intermediate annealing when drawn into fine "fiber" like structure during temper rolling. In annealed sheets, if these fibers fail to recrystalize, the fibers can produce looper lines. Looper lines also can form because of segregated constituent or solute. If the coarse grains with segregation persist the reheating, this can produce looper lines.
Infinite lines can be drawn from a point
They are drawn on the earth as imaginary lines that run from east to west.
Usually state lines are drawn as a dot dash dot line.
they are drawn from east to west
A square by definition has lines of symmetry. Therefore a square cannot be drawn without any lines of symmetry.
uncountable lines can be drawn through one point.
Lines of Latitude
5 lines is symmetry
They are perpendicular lines
This diagram is an example. The bolded lines are the lines you should draw._________ __________|/////////////|////////////////||/////////////|////////////////||/////////////|////////////////||/////////////|////////////////||-----------|-------------|Note: The top solid lines should be drawn, and the dashed lines on the bottom would be drawn, also. The slashes are just filling.
3 lines of symmetry.
Meridians are lines of longitude that are drawn from the North to South poles.
Isohytes are lines drawn on maps joining places of equal rainfall.
If drawn on a globe at intervals of one degree, there would be 178 lines and two points.
They are imaginary lines which are "drawn" on spherical objects. They are parallel to an equatorial line.
There are three lines.
latitude lines are parallel and longitude lines meet at the poles
When someone says "the lines of revolution", this is related to the lines that were drawn when the French Revolution was going on. These were invisible lines, but they were rules not to be broken.
