The diagram shows an incomplete polygon. How do I determine whether it is a regular polygon or not? How should I write my reasoning?

see explanations below.

Step-by-step explanation:

The shown sides are all equal.

If it is a regular polygon, it must have all interior angles equal, and all sides equal.

IF
