| Corner and miter angles for various numbers of sides |
||
| no. of sides | corner | miter |
| 6 | 60° | 30° |
| 8 | 45° | 22-1/2° |
| 10 | 36° | 18° |
| 12 | 30° | 15° |
| 16 | 22-1/2° | 11-1/4° |
A full circle contains 360 degrees. So, to make a closed construction out of straight pieces, the corner angles must add up to 360 degrees. In the simple figure with six equal-length sides shown in the Corner and Miter Angle illustration below, the six 60 degree corners add up to 360 degrees.
But, as shown, 60 degrees is not the angle you need to cut on the ends of each piece. Because two sides come together to make the angle, each side must be miter-cut to exactly half the total corner angle, or 30 degrees.
Here's the rule for finding the angle: To determine the corner angle for a figure with any number of equal-length sides, divide 360 degrees by the number of sides. To find the miter angle, divide the corner angle by two.

I like the fact that you are trying to help us, but, for my limited education, I find your method tedious. I was taught that because you are finding the miter angle to cut.finding the corner angle is a waste of time. Just divide the number of sides into 180 degrees (1/2 of the circle)

Then tape the edges together so that when you glue them up the tape will act like a hinge. Then use some thick rubber bands or some band clamps to hold it while the glue dries.
