5 days ago · A set of two numbers or objects linked in some way is said to be a pair. The pair a and b is usually denoted (a, b), and is generally considered to be ordered, making it a 2-tuple. In certain circumstances, pairs are also called brothers or twins.

A linear pair is a pair of adjacent angles whose non-adjacent sides form a line. In the diagram above, ∠ABC and ∠DBC form a linear pair. The angles are adjacent, sharing ray BC, and the non-adjacent rays, BA and BD, lie on line AD.
A set is a collection of things, usually numbers. We can list each element (or "member") of a set inside curly brackets like this: Common Symbols Used in Set Theory. Symbols save time and space when writing. Here are the most common set symbols. In the examples C = {1, 2, 3, 4} and D = {3, 4, 5} Symbols in Algebra Symbols in Mathematics Sets Index

Learn if they are supplementary and congruent using postulate, axioms, and theorem.
Definition: Two angles that are adjacent (share a leg) and supplementary (add up to 180°) In the figure above, the two angles ∠ JKM and ∠ LKM form a linear pair. They are supplementary because they always add to 180° and because they are adjacent, the two non-common legs form a straight line segment JKL.
