Plane. (That's why a 3-legged stool never wobbles.)
Compared to a 3-legged stool it would. Consider the 3 or 4 points where the bottom of the legs make contact with the floor (which need not be even). Any three points are always in one plane so all points of contact for a 3-legged stool will always lie in the plane, thereby preventing rocking. Four points need not be coplanar and if they are not, the stool will rock.
A triangle is the strongest geometric figure It is not necessarily stronger but it will stand on the ground on all legs when the ground is uneven, unlike a table with more legs

On a four legged chair, if any of the legs are not as long (or longer) as the others, the chair will wobble. On a three legged stoll, if one of the legs are different, the chair will only be uneven or fall over (depending on how drastic the difference is).
no it was a stool and stools cant speak let alone sing.
When you have a four legged stool it can be unbalanced if one of legs is a different length than the others. if you have a three legged stool than even if one of the legs is uneven it will still balance evenly.

A small seat that has three legs as opposed to four (or more)
Three points are the minimum required to define a geometric Plane. Any 3-legged stool, then, can only exist on a single Plane, and cannot alternate between any two Planes (i.e., rock). By combining any 3 of the 4 or more legs on the stool could define a separate plane on which the stool could stand. There are 4 separate configurations of 3 legs upon which a 4-legged table could stand: ABC AB D A CD BCD
As a general rule a chair would have 4 legs, a stool would have 3.

a stool is a seat with three or four legs but with nothing to support your back or arms while a chair is a piece of furniture to sit on with a back, a seat and four legs
Yes. That's why a 3-legged stool never wobbles.
