Water vapor; they are basically artificial clouds formed by the wings.
=======================
They are called con trails.
Overhead distribution lines are made of aluminium not wood.
A number plane is made with two lines which cross at right angles.
Overhead electrical lines are usually made of aluminum, and some have a steel strand added which is used to give the conductor more strength (not to carry current).
A polygon is a plane figure with 3 or more straight sides and angles. A plane figure is a flat enclosed figure made of straight lines, curved lines, or both.
powerlines mounted on pylons, see Overhead power line. For lines carrying information, see Overhead cable. An overhead line or overhead wire is used to transmit electrical energy to trains, trolleybuses
They are made of straight lines, all in one plane, such that pairs of them meet at vertices.
A point is a single spot in space. A line is the connection between two points. A plane is the space made up between three or more lines. A plane has infinite lines and therefore infinite points.
A curvilinear pattern is a curvilinear shape ( a shape made completely of curved lines. no straight lines/edges) repeated across a plane.
If the lines are all in the same plane and they are all straight lines then it is a polygon. Otherwise it has no specific name.
they are made of alluminium
Yes, all geometry planes are infinite and have lines going in every direction, except it doesn't look like that when you see a grid because they only need to include some information for a certain part of a line of the plane. All lines go forever in each direction (left and right), and a grid is made up of lines.
A plane is made up of an infinite number of sides (lines) that are joined at endpoints. This creates a flat surface that extends infinitely in all directions. Each side of a plane is defined by two points.
