a rectangle has 2 lines of symmetry: one runs from the center of one of the shorter sides to the center of the other short side. The second runs from the center of one of the longer sides to the center of the other longer side. Diagonals are not lines of symmetry.
Many textbooks use what is called the folding test to find lines of symmetry of plane shapes. This tests says that when the folded part sits perfectly on top so that all the edges are matching, then the fold line is a line of symmetry. If we use this definition, then a diagonal is not a line of symmetry of a rectangle. We would find 2 lines of symmetry using this definition.
Many books define both reflective and rotational symmetries. In fact, in more advanced algebra we look at groups that deal with this. Here is some interesting info about how that would would work with a rectangle. First you would need to identify the corners of the rectangle by using numbers or letters such as ABCD.
Using this we can see two rotational symmetries and two reflective or line symmetries of the rectangle. Now think of symmetries as a function mapping the points of the rectangle back on themselves. Using this idea we can define the product of these functions or transformations. This would be one symmetry followed by another. A composition of symmetries.
A rectangle has two lines of symmetry, each of which is a perpendicular bisector to two opposite sides of the rectangle.
A rectangle has two lines of symmetry

Are there any line of symmetry in rectangle how many?
A rectangle has two lines of symmetry
Does a rectangle have line symmetry without rotational symmetry?
No A rectangle has rotational symmetry as well
How much line of symmetry does a rectangle have?
a rectangle has 4 lines of symmetry
Does a Rectangle have at least one line of symmetry?
A rectangle has two lines of symmetry, the lines that connect the midpoints of the parallel sides of a rectangle are lines of symmetry of the rectangle.
Does a 4 by 3 inches rectangle have 1 line of symmetry?
The rectangle has 2 lines of symmetry
Which shape has more than one line of symmetry?
Many shapes have more than one line of symmetry. These include a rectangle, equilateral triangle, and a square. While a rectangle has two lines of symmetry, an equilateral triangle has three.
Does a rectangle have a line of symmetry?
yes
Can a rectangle have only one line of symmetry?
No.
How many axes of symmetry does a rectangle have?
a rectangle has 2 axes of symmetry
Does a rectangle have a reflective line of symmetry?
Yes - it has two lines of reflective symmetry.
Which shape has a line of symmetry a isosceles triangle a rectangle or a trapezoid?
An isosceles triangle has exactly one line of symmetry, a rectangle has two. A trapezoid can have none or one.
How many lines of reflectional symmetry does a rectangle have?
A rectangle has two lines of reflectional symmetry. One line of symmetry runs vertically down the center, while the other runs horizontally across the center. These lines divide the rectangle into two identical halves.
