Use a protractor
(n-2)(180) use that formula to find the sum of the interior angles of a polygon in degree
11
140
convex
That depends. What is the length of the sides of the rectangle?
Multiply by 0.0254
add the sides of the polygon.
I do not no how about you find out what a polygon is then count the sides -A
That will depend on how many sides the polygon has.
If the polygon is a regular polygon then all interior angels are equal to 180-(360/no of sides of the polygon)
It is a typo of the word "perimeter"A perimeter is the sum of the distances around a two-dimensional object.
The answer will depend on where the distance to the polygon is being measured from.
you add up the areas of all the faces on the polygon.
any polygon
The formula to find the sum of interior angles of a polygon is 180° × (n - 2), where n is the number of sides of the polygon.
A polygon so described is called a regular polygon. You'll find a link below.
