Answer:
Yes, i believe that the generalization about the measure of a point angle of a star polygon is true.
First we find sum of interior angle of an n-sided star polygon.
number of triangle in a polygon = n - 2
sum of interior angle of a triangle = 180°
sum of interior angle of an n-sided star polygon = ( n - 2 ) × 180°
To find measure of a point angle, we use:
× 180°
To find a point angle we eliminate density by multiplying d by 2 in the formula for finding number of triangle, divide the whole by total number of sides and then multiply by the sum of interior angle of triangle(180°).
Since all the angle of a regular star polygon are equal, we can calculate each pointy interior angle of a regular star polygon using the formula given below:
× 180°
This isn't to diffuclt. So, to the formula for the area of a circle is 
, or instead of r, you can put D, which is r times 2
The diameteris 2.5, so, the answer would be
pi times 2.5, where pie = 3.14
So, the answer is 2.5 * 3.14 = 7.85 or 7.9
