A rectangle has 4 equal angles but is not a regular polygon. So I would say no. However, I cannot think of another polygon that disobeys the rule...?! * * * * * Think laterally. Literally laterally! Consider any regular polygon. Select a side and move it in (or out) parallel to itself. Stretch or truncate it as required. You will then have a polygon that remains equiangular but is no longer equilateral - and so not regular.
The answer depends on the polygon itself and what information you have about it. There are different formulae for different situations.
Triangles, squares and hexagons.
A triangle cannot be parallel because it is a polygon with three sides and three angles, while the concept of parallelism applies to lines. In geometry, two lines are defined as parallel if they never intersect and are always the same distance apart. Since a triangle consists of line segments (the sides) that connect at vertices, the sides can be parallel to other lines, but the triangle itself cannot be described as parallel.
There cannot be a similar polygon by itself. One polygon is similar to another if all of their corresponding angles are equal. This requires that the lengths of corresponding sides are in the same ratio: that is, if one polygon is a dilation of the other.

No, a line is not a polygon. A polygon is a closed plane area bounded by straight sides. A line, by itself, does not contain an area.

A polygon is a plane area which is bounded by straight lines. Its face, therefore, is itself.
A polygon itself doesn't have a specific number of centimeters—it depends on the dimensions of the polygon. To clarify: A polygon is defined by the number of sides it has, not by a specific measurement. The length of each side can be measured in centimeters, but that varies depending on the size of the polygon. For example: A triangle (a polygon with 3 sides) could have sides that are 5 cm each, or 10 cm each, etc. A square (a polygon with 4 sides) could have sides that are 4 cm each, or any other length. So, to answer the question: the number of centimeters a polygon has depends on the lengths of its sides, which is not a fixed property for all polygons.
Fermium can be combined with itself. However, all you'd get is a bigger piece of Fermium.

A 120-degree angle is associated with a polygon that has 3 sides, specifically a triangle, when considering interior angles. However, if you're asking how many sides a regular polygon can have with each interior angle measuring 120 degrees, the answer is a hexagon, which has 6 sides. In this context, the angle itself does not define a specific number of sides, but rather the polygon formed by such angles.
