Give and describe parts of a polygon?
A polygon is a shape constructed by straight lines. Examples: triangle 3 sides, quadrilateral 4 sides, pentagon 5 sides, hexagon 6 sides, heptagon 7 sides, octagon 8 sides ...... etc Polygons can be regular (equal sides) or irregular (unequal sides) Polygons have interior angles that are measured at their vertex. To find the sum of a polygon's interior angles: (number of sides-2)*180 All polygons have a total sum 360 degrees exterior angles.
Why do you calculate perimeter by adding?
Adding the lengths of the straight sides of any polygon will give its perimeter. In the case of regular polygons it will be the length of the side multiplied by the number of sides. But in the case of a non-regular polygon all the individual sides' lengths will be added to give you the perimeter.
What are polygons give example of polygons?
a polygon is a a shape with equal sided shape
What are the name or type of polygon?
A polygon is a closed 2-dimensional shape whose boundaries are straight lines. These are its sides and a polygon can have 3 or more sides - with no maximum number. A 3 sided polygon is a triangle and a 4-sided one is called a quadrilateral. For 5 or more sides, the names are of the form n-gon where n is the Greek prefix for the number of sides. Since the number of sides is limitless, there are infinitely many polygons and so infinitely many names. It is obviously not possible to give a comprehensive list. See the link below for guidance on the prefices. However, you should use prefices for polygons with more than 12 sides only if you want to be unhelpful, obfuscatory or pretentious. If you wish to be communicative and helpful to your reader, it is much better (and wholly acceptable) to refer to a 17-sided polygon as a 17-gon rather than heptadecagon (and that's still a relatively easy name to decipher).
Give me the answer to solve a comple area of complex polygons?
There is no simple answer. There are different formulae depending on the infomation available: side lengths, apothems, angles etc.
