what geometric shape is a tipi?
147264
In general a cone, but not exactly.  A teepee doesn't actually go to an exact point and the large end is less a circle than it is an oval.

diameter x pi\npi=3.14159...\n\nthat's it

There are two names for a seven sided shape, heptagon and septagon.  Both answers are equally correct

A shape with minimum surface area for a given volume!...a round shaped ball-like mass would have minmum area of 4 pi r square for a volume 4/3 pi r cube !

Actually the only way it would be possible is if you use Elliptic or Riemannian geometry, and would require a manifold.  A representation of such a construct would be similar to drawing a 4 dimensional shape in 3 or even 2 dimensions.\n\nEuclidian geometry doesn't allow triangles with a sum of all angles to be greater than 180 degrees.

It is trigonal bipyramidal in shape.                                                    try this & you would understand better                                            take a cardboard or a  paper.cut it in da shape of a triangle. suspend threads from da vertices of da triangle both upward & downward.                                                                                       now catch-hold of da threads.now 1 hand holds da threads from da top. The triangle remains in da mid position & the other hand holds da other 3 threads at the bottom                                            NOW the 2 hands are Cl atoms .THE 3 vertices of da triangle r also Cl atoms                                                                                   Phosphorous is at centroid of the triangle

Corresponding sides of similar triangles are proportionate.

a barb is the pointed end but in truth the tip has got to be curved at either side of it...a normal arrow head is the classic "V " shape easy to pull out of what ever it hit but when its barbed it gets caught ...............especially bad if you get one in your flesh..........thats why you see the cowboy hero in the movies getting the whole arrow pushed through him instead of it getting pulled out.so looking at the answers in here they are half right nobody mentioned about the barbed bit

It's straight ahead geometry.\nDraw a circle with center O.  Draw a diameter horizontally through the circle. Label the left intersect as A and the right intersect as B.  Now draw a vector from O to a point P on the circle.  What tdo you know about triangles AOP and BOP in terms of the angle the vector makes with the diameter?  Use law of sines, law of cosines, trig, etc. to show that angle APO and angle BPO add up to 90 degrees and your done.\n\n\nDoug

Hi I assume you mean an unsymmetrical item. I also assume you want a best fit. I have done similar things on a computer but not by hand. The computer finds three point most distant from the centroid and uses these points as pivots for three orthogonal planes. Not sure of the rest.

You might be thinking of a Reuleaux (or Rouleaux) triangle, but it has rounded sides, not rounded corners.

a cone-shaped object would be described as 'conical'\n\nEveryday objects of this shape:\n\nIce cream cone\nCertain wine stoppers\nSome seeding devices for the garden\nPlant food distributors\nIncence cones\nParty Hats\nCentral part of a lemon juicer

well the radius of the inscribed circle is r=S/p, where S is the area of the triangle (b*c/2) and p is the semiperimetre ((a+b+c)/2); so r=bc/(a+b+c), where b,c are the sides of the triangle and a is the hypotenuse.\nif r is an integral, then a+b+c divides bc, so b and c are of integral type.
