Only when it is a regular polygon that all interior angles are of equal measure
Only if the polygon is "regular".
All of the angles are equal in a "regular" polygon. (All of the sides are too.)
They may, or may not, be equal. If you are talking about a regular polygon, all angles are equal in measure. If it is not a regular polygon, the angles are most likely different.
The perimeter is a measure of distance equal to the sum of all sides of a polygon.

a "regular" polygon
Only if the polygon is "regular".
A rhombus has four sides of equal lengths. So it is an equilateral polygon. But it is not an equiangular. It's angles are not equal in measure.
Only if the polygon is a "regular" one.
All of the angles are equal in a "regular" polygon. (All of the sides are too.)
They may, or may not, be equal. If you are talking about a regular polygon, all angles are equal in measure. If it is not a regular polygon, the angles are most likely different.
The perimeter is a measure of distance equal to the sum of all sides of a polygon.
A regular hexagon which has 6 equal sides and 6 equal angles.
Only when the polygon is a regular convex polygon. Such as an equilateral triangle, or a square, or a regular pentagon.
A regular polygon has sides of equal length and each interior angle is the same measure
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.
