Adjacent corners of a square share one side. Opposite corners share no sides.
A triangle is the only polygon with 3 corners (vertices). There is no polyhedron with 3 corners.

True oval have no sharp corners
No sharp corners to poke yourself on.
I guess shapes that have few sides have sharper angles for instance a triangle has very sharp corners whereas a henagon has corners but they are very rounded.
So the riders don't die.

the colour of pattern may not be the same as that of casting,sharp changes are not provided on patterns but it provided on casting with the help of machining,the material of the pattern is not necessarily same as that of casting.
It is a polyhedron.
Poor handling on the sharp corners.

In music staff a "natural" is used to cancel out a sharp or flat, it only affects the note it appears by. Following notes will be sharped or flatted unless another natural accompanies them. A natural looks like a sharp "#" with the outer corners removed.
