Final answer:
The relation r has reflexive, symmetric, and transitive properties.
Step-by-step explanation:
The relation r defined as (x,y) r (p,q) is a mathematical relation that has certain properties. The properties of this relation are:
- Reflexive property: Every element x is related to itself in the relation r, which means (x,x) is in the relation.
- Symmetric property: If (x,y) is in the relation, then (y,x) is also in the relation.
- Transitive property: If (x,y) is in the relation and (y,z) is in the relation, then (x,z) is also in the relation.
These properties define how elements are related in the relation r.
