I don't follow. The figure is perfectly symmetical. How can the central octagon not have eight 135 degree inner angles? Sunuvagun. So... -
Charles Link replied to the thread I Geometry problem of interest with a 3-4-5 triangle.It surprised me at first when I computed the angles between two of the lines. I thought I would get the result that the tangent of the...

Charles Link replied to the thread I Geometry problem of interest with a 3-4-5 triangle.For the octagon in the center, all sides are the same length, but the angles alternate as mentioned previously, (post 4), so it is...

Charles Link replied to the thread I Geometry problem of interest with a 3-4-5 triangle.Thank you @DaveC426913 <3 for the above diagram (post 18). The video on this is very incomplete, claiming that the triangles are of...

That looks like an origami 'diamond' base. Almost; not quite.

I couldn't see the video either, but following your early posts, especially Posts 2 & 4, I was able understand how this procedure...

Charles Link replied to the thread I Geometry problem of interest with a 3-4-5 triangle.@DaveC426913 Start with a square and draw lines from all four corners to the midpoints of the two other sides of the square. I don't...

Charles Link replied to the thread I Geometry problem of interest with a 3-4-5 triangle.The video just shows only one, but if you draw all of the lines connecting the four corners to the midpoints of the other sides, you...

Charles Link replied to the thread I Geometry problem of interest with a 3-4-5 triangle.It may be stating the obvious, (for the inscribed circle of the triangle of post 10), but with the base of 14, where the center of the...

Have you tried a 13,14,15 sided triangle? You can guess the radius.

Charles Link replied to the thread I Geometry problem of interest with a 3-4-5 triangle.Very clever. I see for that one you have a base of 14, that can be split into 5 and 9, so that the height of the triangle is 12...
