When it has two sets of parallel lines
It is possible for all nine lines to be perpendicular to at least one other line.
One line is a projection that maintains accurate distances from the center of the projection or along given lines it is called an equidistant projection. Another line is a cylindrical projection which projects information from the spherical Earth to a cylinder.
When it has two sets of parallel lines
There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
Sets of numbers that show where lines of latitude and longitude meet are called coordinates. Coordinates are used to specify exact locations on the Earth's surface.
