In Geometry, a figure is claimed to be symmetrical when it is split into two similar halves through the aid of a line. These lines are dubbed the currently of the contrary of a form or figure.A heat of symmetry constantly cuts the shape right into two same and similar parts. There space different varieties of symmetries for a shape like direct symmetry, winter symmetry, reflectional symmetry.
You are watching: How many line of symmetry does a rectangle have
Let united state read much more about the lines of symmetry in a rectangle. We recognize that arectangle is a special parallelogram who opposite sides are equal and also parallel. A rectangle has actually 2 currently of symmetry. Let us learn how to uncover the present of the contrary in a rectangle.

There are two lines of the contrary in a rectangle. As soon as one heat is drawn through the center along the length and the other is attracted along the broad (breadth), we acquire the 2 lines the symmetry. By act this, we get four equal and matching shapes. This deserve to be tried the end by taking a rectangular piece of paper. This is a simple technique of folding through which us can uncover out if a shape has a line of the opposite or not. If the folded component is placed precisely on the various other one, then that folding line is dubbed the heat of symmetry. The figure shown below shows the currently of the opposite of a rectangle follow me its length and also width. Each fifty percent is put on the other as soon as the rectangle is folded follow me the currently of symmetry. First, fold the document horizontally to examine the first line the symmetry and also observe the size and also shape of the equal halves. Then, wrinkles it vertically to examine the 2nd line of the opposite to see the other identical halves.
It need to be provided that the diagonals of a rectangle can not be taken together lines that symmetry as they perform not type equal matching shapes. Now, let us observe the following figure which reflects why a rectangle walk not develop two halves once folded across the diagonal. This is because, once we wrinkles the rectangle follow me the diagonal line, we execute not get two identical halves.
If a number or a flat shape is rotated along its axis and it still appears to be the exact same as before, we call it rotational symmetry. In various other words, ~ above partial rotation, if the shape stays the same as before, climate there is rotational symmetry.A rectangle has actually a rotational symmetry once it is rotated by 180° and also 360° ~ above its axis. When a rectangle is rotated, it fits exactly on the boundary 2 times, once at 180° and once at 360°. In a rectangle the size is better than its breadth, therefore we have the right to say that there is no rotational symmetry in ~ 90° and also 270°.
Topics pertained to Lines of symmetry in Rectangle
Example 1: examine whether heat 1 and line 2 significant in the number are the currently of the contrary in the rectangle offered below. Justify your answer.Solution:When the rectangle is folded follow me line 1,each of the parts developed by the line do not superimpose each various other completely. The same thing happens as soon as we fold it follow me line 2. So, we have the right to say that line 1 and line 2 are not the currently of symmetry because that this rectangle.
Example 2: What space the angles at i m sorry a rectangle has actually rotational symmetry?Solution: A rectangle has actually rotational symmetry at 180° and 360°.
