A square is a closed plane figure bounded by 4 straight lines which are of equal length and which meet one another at right angles. Anything else is non-square.
The principal square root is the non-negative square root.
I have never before heard of a non-perfect square but I suppose it would be any non-zero number that is not the square of an integer. People sometimes say "perfect square" to mean an integer that is a square of an integer - I think the "perfect" is redundant but if you do not think "square" is clear by itself, say "integer square."
any number (including fractions, square roots and Pi) that are not 0 and are not square roots of negative numbers.
It is not a perfect square.
It is not a perfect square.
'Square feet' is a plural term for square foot. A square foot is unit of measurement. It used to measure areas. It is a non-SI (System De Interantionale) and a non-metric unit. It is known as United States customary unit or Imperial unit. A square foot is an area covered by a square.You use square feet for units when you calculate area.
Any shadow cast by a square is non-circular.
No. 2.25 = 1.5^2 is a non-perfect square but it is rational.
It doesn't mean anything. If you've actually seen the term used by a mathematician (which I doubt), you might be able to determine from context what it means, but without that context it's pointless to even try."Square root" has a specific meaning, but "non-square root" could mean that the number in question is not a square root (ludicrous... every number is the square root of something), or that it's not the square root of a given number (an almost equally useless concept), or that it's a root of some kind but not a square root (just tell us what kind of root it is. Cube? Fourth?).
Irrational numbers are pi(3.14...), a non-terminating decimal with no pattern(ex.-0.3456789...), and non-perfect squares(ex.-square root of 34).
It can be. 7 is a non-perfect square and, being an integer, it is rational.
a non rigid is a square and a hexagon
