Does a rectangle have 2 or 4 lines of symmetry?

Let’s recall that a rectangle is a special parallelogram whose opposite sides are equal and parallel. A line of symmetry must cut the shape into two identical parts. A rectangle has 2 lines of symmetry.

How do you draw a line of symmetry of a rectangle?

A rectangle cannot have a diagonal line of symmetry like a square because the sides are not the same length. If you fold this rectangle diagonally so that Corner A meets Corner D, the sides would not match. Try it with a piece of notebook paper! You can draw lines of symmetry on many different figures.

How do I find the line of symmetry?

To find the line of symmetry algebraically, you need to identify if the equation is written in standard form or vertex form. Standard form is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.

Does a rectangle always have a line of symmetry?

A rectangle has 2 lines of symmetry which divides it into two identical parts. A shape can be two or more lines of symmetry. To recall, a rectangle is one of the quadrilaterals whose two opposite sides are equal and parallelogram.

Can a rectangle be taken as a line of symmetry?

The diagonals of a rectangle cannot be taken as a line of symmetry as they do not form equal matching shapes. This can be tried out by taking a rectangular shaped piece of paper and folding in half both horizontally and vertically to check if both the halves are equal in size and shape.

How to find the symmetry of a shape?

Folding Test. You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry.

When is a fold line a line of symmetry?

When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here I have folded a rectangle one way, and it didn’t work. But when I try it this way, it does work (the folded part sits perfectly on top, all edges matching): A Triangle can have 3, or 1 or no lines of symmetry:

Are there lines of symmetry in a square?

For a square, all of its sides are equal, opposites sides are parallel to each other and the adjacent sides are at a 90°. Thus, in addition to the two lines of symmetry lines like that of a rectangle, a square also has symmetry lines along its diagonals.
