They are lines of constant latitude, all parallel to the equator.
there are two names i can think of: lines of latitude and also parallels
All parallels of latitude are parallel to all others.
The equator is one of them.
Those are the so-called 'parallels' of constant latitude.
Lines of Latitude
Those are the parallels of latitude.
They are lines of longitude.
Latitude lines are the ones which are parallel to each other, with 0º being the Equator Longitude are the ones which radiate out from the poles and which get wider as they approach the Equator. 0º runs through Greenwich, near London.
By definition, a line of longitude is an imaginary great circle on the surface of the earth passing through the north and south poles at right angles to the equator such that "all points on the same meridian have the same longitude".Therefore, all lines of longitude meet at a point at each of the poles.
No. These are called lines of longitude or meridians, one of which is the Prime Meridian running through Grenwich, England (and other places, of course), considered to be 0º longitude, thereby marking the beginning point for all other lines of longitude.The equator, on the other hand, is an imaginary line circumnavigating (running around) the globe at a point halfway between the two poles - in other words, it is crossed by the meridians at right angles.The equator, therefore is a line of latitude from which the degrees north and south of all other lines of latitude are measured. The equator is 0º latitude.
No sir it is not. The equator is the imaginary line that goes horizontally (left to right) around the Earth. London is a city in Europe, all of Europe is above the equator.
Every meridian is an imaginary semi-circle between the north and south poles. There are an infinite number of them, each one is more than 12,000 miles long, and every point on the same meridian has the same longitude.

normal lines or normals
Lines of latitude are any of the circles, called parallels, that are to the north or to the south of the equator and parallel to it. They are the lines on standard maps that go from east to west; right-left.It is an imaginary line around the Earth parallel to the equator.
They are force field lines at right angles to each other as depicted in the related link.
Perpendicular lines meet at right angles
All of them. If its truly intersecting lines, they have to form right angles. All of them. If its truly intersecting lines, they have to form right angles.
By definition, a line of longitude is an imaginary great circle on the surface of the earth passing through the north and south poles at right angles to the equator such that "all points on the same meridian have the same longitude".Therefore, all lines of longitude meet at a point at each of the poles.
Perpendicular lines form right angles when they intersect.
two lines that are perpendicular form right angles
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.
Perpendicular lines form right angles at their intersections.
