1). They are both intervals on the curved surface of a sphere, so units of linear measurement
would not do the job.
2). In the case of longitude, all longitudes merge (come together) at the north and south poles.
So the distance represented by 1 degree of longitude is not the same distance everywhere. It
depends on your latitude.
They are meausered in angles and hence expressed in angles
Latitude and longitude are angles, so they can be expressed in any angle units. Possibilities include radians, degrees, grads, etc. Out of tradition that goes back to the ancient Greeks who invented geographic coordinates, they're virtually always expressed in degrees and their sub-parts. Sub-parts of degrees can be either decimal degrees, or the clunky and unwieldy minutes and seconds.
The lines don't measure anything, any more than the marks on a ruler do. Latitude and longitude are angles on the Earth's surface, measured between zero- references and the location you're trying to find or describe. Some maps and globes have some latitudes and longitudes marked on them, to help you estimate the angles. Just like the marks on a ruler.
Latitude and longitude are angles, and can be expressed in any angle unit. The 'degree' and its sub-divisions have always been the most popular.
they are measured in degrees
The lines printed on some globes and some maps have no names, any more thanthe lines on rulers and tape measures have. They're all used to show the positionof a few even multiples of some units of measurement.The lines on a tape measure mark off multiples of inches, feet, meters, or yards.The lines on a measuring cup mark off multiples of ounces or liters.The lines on maps and globes mark off multiples of angle degrees. The anglesrepresent longitudes if they're marked off in the east/west direction, and latitudeif they're marked off in the north/south direction. Longitudes and latitudes aremeasurements of angles that describe the location of places on the Earth.

You don't. Latitudes and longitudes are angles, whereas meters are used to describe lengths and distances. There are methods to calculate the distance between one latitude/longitude and another. They're straightforward and not 'difficult', but they're far too complex to describe here, and are almost always done with calculators or computers nowadays.
Latitude and longitude are angles that describe the location of a point on the Earth's surface. Longitudes range from zero to 180 degrees east or west. Latitudes range from zero to 90 degrees north or south. There are no official 'lines'. Some maps or globes have some lines printed on them to show where a few latitudes and longitudes are, and other maps and globes have no lines at all printed on them. I have mapping software that can print 324,000 latitude lines and 648,000 longitude lines if I want them, but I have never needed them yet.

Angles that are always congruent are applesauce angles
Angles that add up to 180 degrees are always supplementary
Any angle can be measured in degrees or in radians.But the question seems to be: What are corresponding radian measures for the angles expressed in degrees? To that question there is no answer because the possible list of "degree angles" to be expressed in radians would be unlimited.
vertical angles
right angles
the shape? no, not always. but they are always at least similar figures. but the angles alone are always congruent
Supplementary angles are angles whose sum always equals 180 degrees.
The Prime Meridian is an imaginary line. All longitudes are reckoned as angles from it, and all parallels of latitude cross it.
