    Can one determine the surf/circumf with a geometrical figure

    Well, it seems like Simon is getting ironic... I don't know why that's necessary. I just wondered why the angle was 17.686... and not another one. Just like pi = 3.1415... and no-one knows why. Nothing mystical about, but just interesting. Point is I DID found the only kite with the 3...

    Can one determine the surf/circumf with a geometrical figure

    Well, to make a long story short: the answer to why 17.656... is because [SIZE="4"]atan (1/pi) = 17.65678715141288.. (thanks to Simon.)

    Can one determine the surf/circumf with a geometrical figure

    to Simon: but it is the only one whose area is the same as the area of the circle ! That has been my statement all allong! The question is: why is that so and why does it give that kite with angle 17.656...(or angle C 144.686...) What's the relationship between that (those) angle(s)...

    Can one determine the surf/circumf with a geometrical figure

    Hello Simon, thanks for the extended answer. I think you should look at my blogsite with the drawings and calculations to see what I ment. We're talking 2 directions. It's not a box with edges pi*r and r but those with cos and cos/tan edges. I think my representation of the kite is the...

    Can one determine the surf/circumf with a geometrical figure

    Thank you HallsofIvy for answering. But I can't believe you, sorry. I think there's just 1 kite: The kite which has 2 arms equal r and 2 arms equal πr and an area equal the area of a circle. Other angles can't give that I think.(I tried several) If you can give me an example of...

    Can one determine the surf/circumf with a geometrical figure

    because the angles inside the triangle ABC must sum to 180 degrees I understand yes. But why 17.686 and not 15.3 or 26.88 What's the relation of 17.6...to a circle or pi or so?

    Can one determine the surf/circumf with a geometrical figure

    Simon thanks for welcoming me! I have never seen a circle being kited! I added some new drawings, (logically): "rectangling the circle" and "boxing the circle". The big question is: why this angle of 17.65678715141...?

    Can one determine the surf/circumf with a geometrical figure

    Exists in mathematics a geometric figure, with straight lines (rectangle, parallelogram, or so), allowing you to determine the circumference and area of a circle by drawing / calculating / approximating? Without pi or formulas. So figure with no curved lines (and no polygons). for instance...
