Difference between boundary fill algorithm and scanline polygon fill algorithm?
in scan line polygon fill, each can line crossing a polygon, the area fill algorithm locates the intersection point of the scan line with the polygon edges. These intersection points are then stored from left to right and the corresponding frame buffer positions between each intersection painr are set to the specified fill color. In boundary fill, approach to area filling is to start at a point inside a region and paint the interior outward toward and the boundary.
How do you overcome limitations of stacks in polygon filling?
You overcome limitations of the stack in polygon filling, or in any other algorithm, far that matter, but using an iterative technique, rather than a recursive technique. Recursion is quite useful, and can simplify algorithm design. Polygon filling, however, is a class of algorithm can potentially have a very deep recursion depth. This causes stress on the stack, hence the need for iteration.
Which programming language can be used for calculating area of a polygon?
Any of them. Calculating the area of a polygon is a relatively simple mathematical task.

What is the name for a polygon?
A polygon is not a specified shape, the word polygon actually means many sides; so a triangle and a decagon are both polygons.

How do you calculate the minimum bounding box of a convex polygon?
With the two rotating calipers algorithm: http://cgm.cs.mcgill.ca/~orm/rotcal.html
How do you write a function in Python to calculate the perimeter of a regular polygon of N sides and use that to approximate Pi by increasing N until Pi?
You can find a description of the algorithm in the Wikipedia article titled "Liu Hui's π algorithm".
How many angle of polygon?
Many. Poly means many and a polygon is a plane figure bounded by three or more straight lines. The precise number is NOT specified. Since the number of angles in a polygon equals the number of lines, the number of angles is also unspecified.
What does a 10 sided polygon look like?
10 sides 10 corners (vertices), no intersecting lines a closed figure.The sides&angles are not necessarily equal, unless a regular polygon is specified. A five-pointed staractually is a 10-sided polygon (There are 5 vertices pointing 'out' and 5 pointing 'in').
How do you you find the measure of a angle?
That's a very unspecific question. Is it just an angle? Is it part of a polygon? Are the measurements specified? You could measure it with a protractor if that's what you're asking.
What is a polygon with equal sides and angles is a what polygon?
it seems to me that the only polygon of your description is a square
