Question 222558: how many angles are there in a 100-gon???-i Answer by Alan3354(69443) (Show Source):

how many diagonals total could be drawn in aregular 100-gon The 100-gon has 100 vertices. The # of connecting line segments is 100C2 = (100*99)/(1*2) = 50*99 = 4950

you have to scroll about halfway down the page to get to the gon names. the sum of the interior angles of a polygon is equal to (n-2) * 180. for example, the sum of the interior angles of a triangle is (3-2) * 180 = 180 and the sum of the interior angles of a quadrilateral is (4 - 2) * 180 = 360 and the sum of the interior angles of a pentagon ...

Question 392784: The measure of each interior angle of a regular polygon is 20 degrees more than 3 times the measure of each exterior angle.

To get 4 km^2 on 1:100 scale, the side has to be 2 km and at 1:100 scale that is 20 m, so the map area would be 400 m^2 or 400m^2*100cm/m*100 cm/m=4,000,000 cm^2
