A dodecagon is a regular polygon that can be drawn using rotations. These are normally drawn in a Geometer's Sketchpad.

A regular polygon can be drawn using rotations by employing the concept of symmetry around a central point. For example, to create a regular hexagon, one can rotate a line segment around a central point by angles of 60 degrees. This process can be repeated for any regular polygon by rotating a starting line segment by the angle defined by 360 degrees divided by the number of sides of the polygon. Thus, regular polygons such as triangles, squares, pentagons, and hexagons can all be constructed using rotation.

The area of a regular polygon is given by the following formula: area =(1/2) (apothem)(perimeter).There are several other formulas that can be used. Regular Polygon Formulas are: N=number of sides, s= length, r = apothem (adiius of inscribed circle) R = radius of circumcircle. Using any of these formulas you can find the measurements of a regular polygon.
A regular or irregular polygon is a plane shape with straight sides.Measure the internal angle of all corners using a protractor.

No. Regular tessellations use only one polygon. And, according to the strict definition of regular tessellation, the polygon must be regular. Then a tessellation using rectangles, for example, cannot be called regular.
that it could be drawn using just a compass and straight edge
A regular tessellation is one in which a plane is covered, without gaps or overlaps, using copies of a regular polygon.

Expressed using systematic polygon names, an 83-sided regular polygon would be called an octacontakaitrigon.

Euclid discovered pi
The apothem ( a ) of a regular polygon can be found using the formula ( a = \frac{s}{2 \tan(\pi/n)} ), where ( s ) is the length of a side and ( n ) is the number of sides. Alternatively, it can also be calculated using the formula ( a = \frac{A}{P/2} ), where ( A ) is the area of the polygon and ( P ) is the perimeter. The apothem serves as the height of the isosceles triangles formed by connecting the center of the polygon to its vertices.
The sum of the interior angles of a regular polygon can be calculated using the formula (n-2) * 180, where n is the number of sides. For a regular 20-sided polygon, the sum of the interior angles would be (20-2) * 180 = 3240 degrees.
