Is a star a regular polygon or a polygon?
I think regular. * * * * * Only if you ignore all the points where the sides cross one another.
Can the sides of a polygon cross?
No the sides of a polygon can not cross

What is the sum of the interior angle of a 13-sided polygon?
The sum of the interior angles of a triangle is 180 deg. For a convex polygon with n sides we can divide it to n-2 triangles. So the answer, if the polygon is convex, is (13-2)*180= 1980 deg * * * * * The polygon need not be convex. The formula for the sum of the interior angles is valid as long as the polygon is simple - that it, its sides do not cross each other inside the polygon.
Can the sides of a polygon cross?
No the sides of a polygon can not cross
Do you calculate the interior angles of regular and irregular polygons the same way using the number of sides - 2 times 180 degrees n-2180 sum of interior angles. A Pentagon would 5-2?
All triangles have 180 degrees, all quadrilaterals have 360 degrees, no matter what the kind of triangle or quadrilateral. The formula would hold true for all polygons. Prove this by drawing diagonal lines in a polygon (do not cross one diagonal with another) to divide the polygon into quadrilaterals and/or triangles. Then add the degrees in the quadrilaterals and triangles in your polygon. This should give you the correct number of degrees. If you have a many sided polygon, it is necessary to use the formula, because the figure would be very difficult to draw. Formula- Number of sides minus 2, times 180 degrees. (n-2) X 180= degrees in a polygon
How can you use a coordinate plane to draw a polygon?
You do not need a coordinate plane to draw a polygon. A polygon is simply a plane shape whose boundaries are straight line segments that meet at their ends but do not cross. So draw any number of points and draw straight ines from one to the next, and on to the next, and so on except that you must not cross an existing line and the last line must end at the starting point.

Which cross is on the British flag?
There are three crosses: The St. George's cross - the vertical, horizontal red cross. The St. Andrew's cross - the diagonal white cross on blue field. The St. Patrick's cross - the diagonal red cross.
Heraldic symbol in the form of a diagonal cross?
The Heraldic symbol in the form of a diagonal cross is called a Saltire, formed by a "bend" and a "bend sinister".
What is the sum of the interior angles of a polygon with seven sides?
In any polygon, regardless of the number of sides, the sum of the angles is always 360 degrees, as long as none of the lines that make up the sides cross over each other.
