It seems like you might be asking about the interior angle sum of a polygon with a certain number of sides, potentially referring to π. However, the term "π side" might be a bit unclear, so I'll clarify.

The interior angle sum of a polygon depends on the number of sides $n$ it has. The formula to calculate the sum of the interior angles of a polygon is:

$\text{Sum of interior angles} = (n - 2) \times 180^\circ$

If you are referring to a polygon with $n$ sides such that each side corresponds to a length or a geometric property related to $\pi$, the number of sides $n$ determines the interior angle sum, not the length of the sides themselves.

If you meant something else, please clarify. Otherwise, here’s an example:

• For a triangle (3 sides), the sum of interior angles is: $(3 - 2) \times 180^\circ = 180^\circ$

• For a quadrilateral (4 sides), the sum is: $(4 - 2) \times 180^\circ = 360^\circ$

If you clarify the question further, I can provide more precise information.

Would you like further details, or do you have any other questions? Here are some related questions that might interest you:

1. What is the formula for finding the interior angle of a regular polygon?
2. How do you calculate the exterior angle sum of a polygon?
3. How does the number of sides of a polygon affect its angle properties?
4. Can a polygon have a side length of π?
5. How do the interior angles of a regular polygon compare to those of an irregular polygon?

Tip: The sum of the exterior angles of any polygon is always 360°, regardless of the number of sides.
