Its 4 just like a square

No it is not. The diagonals of a square are lines of symmetry; not so with a rectangle. So there are only 2 lines of symmetry.

In theory, the statement made by the User above^^^ is true, but when it comes to the decisive moment where one has to create structures, or anything that might save or take away lives, that fails... In a rectangle, if you make diagonals, the rectangle will be split into 2 equal length, equal size, right triangles. These people have made the common misconception of trusting a textbook entirely for their answers. Textbooks are written by humans, and humans make mistakes. If everyone understood this, 9/11 never would have happened.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Ellipses and non-square rectangles have two lines of symmetry.


Why are diagonals not lines of symmetry in rectangles?

The diagonals of rectangles are rotational lines of symmetry but not reflective. To be reflective lines, folding along the line has to give the same shape on each side.

How many lines of symmetry does a parallelogram have?

Squares, which are parallelograms, have four lines of symmetry. Rectangles have only two. Rhombi have two lines of symmetry. Generic parallelograms don't have any lines of symmetry.None normally unless it is in the shape of a rectangle in which case it will have 2 lines of symmetry
