I'd hate to give you a definition like, "Related pairs of numbers are pairs of numbers that are related" so let's just go with an example. Let the first number of a pair represent a quantity of bicycles. Let the second number represent the number of tires per bicycle. With 1 bicycle you would have 2 tires, with 2 you would have 4 and so on.
(1,2)(2,4)(3,6)(4,8) are related pairs of numbers.
Number of factor pairs = number of rectangles
Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.
An analogy is a relationship between two words. Then, a third word is given to find a a word that is related to the third word in the same way the first two words are related.
3 pairs
A cube has six pairs of intersecting line segments. These six pairs will total 72 lines in a cube.
One to one.

"Dose" is a measured portion of a medicine. I am not aware of any factor pairs related to dose 18 or any other measured quantities of medication!18 does have 3 factor pairs.
Cephalic refers to the head. The appendages related to eating include the mandibles and two pairs of maxillae. There are also three pairs of maxillipeds that move food towards the mouth.
Amicable pairs are two numbers that are related in such a way that total of the divisors of each is the same as the other number. This is the case of numbers 220 and 284.
"Dose" is a measured portion of a medicine. I am not aware of any factor pairs related to dose 27 or any other measured quantities of medication!27 does have 2 factor pairs.
Woodlice have 7 pairs of legs. They are crustaceans, and very closely related to crabs.
