Do you still need the answer??
Answer:
The two features are Cooperation and Responsibility
Explanation:
<em>Dyads</em> relationship is a type of relationship where by the social group consist of two people only while a<em> Triad</em> on the otherhand is a relationship where three people are involved.
The ability <em>to have cooperation between the two people leading to loyalty by one partner and a sense of responsibility between them to see towards the success of the relationship irrespective of its instability are what makes them (Dyads) most intimate social relationship.</em>
On the otherhand, these features changes when the relationship changes from dyads to triads. The <em>cooperation would no longer be there</em> as a result of one person having an option to establish a social interaction.<em> Lack of</em> <em>loyalty is common when a relationship becomes a triad</em>. Also, there would be<em> lack of sense of responsibility to see towards the success of the relationship</em>. There is a possibilty of one person leaving the group if feedup rather than trying to resolving the issue (as a result of lack of reponsibility).
