Find the angles of a skinny hexagon without algebra - simple math

[durangod]

Hi, i dont know algebra so i was wondering if this can be done via simple math.

I was buiding a frame for the back side of my shed door which is a rectangle divided into an upper and lower half by a horrizontal support and then the lower half is disected diagnally with another support board.

Took me forever in google to find the actual name for this type of support board, i finally found it on this website..

The one i am doing is the skinny hexagon where it fits into each corner.

The problem is that the math is too complicated for me. I did the lower half today by trying 45 deg and 45 deg on both sides (and both ends) of the board but it still did not come out flush inside the box. I cut the board longer than the diag measurement just in case. So what is the correct angle and how to figure it in simple math?

Thanks so much

Dave

The site shows all the math; it is not "simple", and can't be made any simpler, but has been reduced to formulas you should be able to evaluate. The hardest part is the little bit of trigonometry you will have to know, in order to use a calculator to do parts of the calculation. You need a "scientific calculator" to do this, but most computers or devices have such an app, or can get one.

Can you tell us the numbers you have for L1 and L2 (the width and height of the interior)? Then we can help you with the specifics of the calculation.
