WebState/calculate the number of sides of the polygon. ABC ABC has 3 3 sides and so it is a triangle. 2 Determine the size of the angles and/or side lengths within the polygon. As BCA = 116° BC A = 116°, angle ACD = 180 - 116 = 64° AC D = 180 − 116 = 64°. WebSo here we can see that the sum of all of the internal angles in our polygon can be represented as seven triangles. To find the value of an internal angle within this polygon, we can just multiply the number of triangles by 180 °, then divide by the number of internal angles, which is nine. Excellent!

WebIf you want a different orientation, you just need to add a constant angle. So the general form is: x [n] = r * cos (2*pi*n/N + theta) + x_centre y [n] = r * sin (2*pi*n/N + theta) + y_centre Share Improve this answer Follow answered Aug 25, 2011 at 22:58 Oliver Charlesworth 266k 32 561 677 WebA regular hexagon can be divided into six equilateral triangles.
