Only when it is a regular polygon that all interior angles are of equal measure
Only if the polygon is "regular".
If all of its interior angles are equal then it is a regular polygon
Only when the polygon is a regular convex polygon. Such as an equilateral triangle, or a square, or a regular pentagon.
A regular hexagon which has 6 equal sides and 6 equal angles.
A regular polygon.
It will have 4 sides which could be a square or a rectangle
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1980 degrees.
This is a tautological question that does not have a proper answer. A regular polygon is one which has all its sides of equal length and all its interior angles of equal measure.
Only if it is a regular polygon.
The polygon will have 12 equal sides and each interior angle measures 150 degrees.
