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
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1980 degrees.
The polygon will have 12 equal sides and each interior angle measures 150 degrees.
Only when it is a regular polygon that all interior angles are of equal measure
Only if the polygon is "regular".
Only if the polygon is a "regular" one.
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.
If all of its interior angles are equal then it is a regular polygon
A regular hexagon which has 6 equal sides and 6 equal angles.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1980 degrees.
It will have 4 sides which could be a square or a rectangle
A regular polygon.
The polygon will have 12 equal sides and each interior angle measures 150 degrees.
Only if it is a regular polygon.
A polygon that has 3 sides 2 of which are of equal length and 3 interior angles 2 of which are of equal measure.
