Yes, you can compare two distances in geometry. Here are some ways to do it: http://www.regentsprep.org/regents/math/geometry/gcg3/ldistance.htm
In normal geometry, it's not possible to make a triangle with two obtuse angles. It is possible to make a triangle with two obtuse angles in spherical geometry -- it's a kind of "spherical triangle". It is possible to make a triangle with two obtuse angles in some kinds of non-Euclidean geometry -- it's a kind of "non-Euclidean triangle".
Answer The two commonly mentioned non-Euclidean geometries are hyperbolic geometry and elliptic geometry. If one takes "non-Euclidean geometry" to mean a geometry satisfying all of Euclid's postulates but the parallel postulate, these are the two possible geometries.
Yes it is possible to compare two different databases. All you have to do is implement the right script which will compare the information and the structure of the databases.
No. It is not possible in Euclidean planar geometry (if you don't know what that means, it means "the only kind of geometry you've ever heard of") for a triangle to have two obtuse angles.
Pints measure volume, and meters measure lengths/distances. Can't compare the two
Not in Euclidean geometry, but in other geometries such lines are possible.
Yes it can. Actually in non-euclidian geometry its possible that two parallel lines may form a angle, but it can never be possible in convention euclidian geometry (in which some of angles of a triangle is always 180 degrees, etc., such things are not sure in non-euclidian geometry).
Plane Geometry and Solid Geometry
In Euclidean geometry, if and only if they are parallel.
Oh, dude, like, you can totally determine two possible locations for the epicenter from two epicentral distances. It's like a math puzzle, but with earthquakes. So, yeah, if you have two distances, you basically have two circles intersecting, and where they meet is where the epicenter could be. It's not rocket science... well, actually, it kind of is, but you know what I mean.
Yes. You can use this to prove that two lines are parallel, in analytic geometry, i.e., geometry that uses coordinates.Yes.
