A line (drawn at any angle) that goes through its center is a Line of Symmetry. So a Circle has infinite Lines of Symmetry.

Quadrilateral ABCD has two pairs of adjacent sides of equal length, and one pair of angles of equal measure. It also has one line of symmetry. It has no parallel sides. Quadrilateral ABCD is a kite.
Here you will learn about lines of symmetry, including symmetry properties within polygons, angle properties, and symmetry of different line graphs. Students first learn about line symmetry in grade 4 with their work with 2D shapes in geometry.
For example, if the kite rotates 9090 degrees clockwise about it’s centre, the line of symmetry will still be the longest diagonal as the line of symmetry moves with the shape. Also, lines of symmetry do not have to go through two vertices.

Rotational symmetry is when an object has been rotated but it looks like it is in its original orientation. For example, a square will look the same when it is rotated a quarter turn. A shape does not have rotational symmetry if it does not look the same when rotated. For example, a kite has no rotational symmetry. Below is a square showing rotatio...
The order of rotational symmetry (or degree of rotational symmetry) is the number of times an object looks the same when it is rotated a full turn of 360°. The shape must look as though it has not rotated at all. For example, a rectangle has rotational symmetry of order 2. When it is turned 180° and 360° it looks the same as when it is at its start...
To find the order of rotational symmetry: 1. Rotate the shape one full turn. For example, find the order of rotational symmetry for this shape. Step 1 is to rotate the shape around one full turn. Step 2 is to count the number of times the shape looks the same as before it was rotated. This is when it fits into its original outline. The diagram abov...
To find the order of rotational symmetry with tracing paper: 1. Place the tracing paper over the shape. For example, use tracing paper to find the order of rotational symmetry for this equilateral triangle. First place tracing paper over the shape. Then draw around it. Then rotate the paper a full turn, counting the number of times that the drawing...
Capital letters of the alphabet with rotational symmetry are : H, I, N, O, S, X, Z. These letters all have rotational symmetry order 2 because they look the same after rotating half a turn and a full turn. All of the other capital letters of the alphabet have no rotational symmetry. The only letters of the alphabet with rotational symmetry are H, I...
Rotational symmetry is how many times a shape fits into its original image when rotated a full turn. Reflective symmetry (or line symmetry) is the number of lines of symmetry pass through the centre of the shape so that both sides of the line look the same. The order of rotational symmetry is not the necessarily the same as the order of reflective ...
The angle of rotational symmetry is the smallest angle that a shape must be rotated to fit within its original outline. When rotated through this angle, it must look as though it has not been rotated at all. The angle of rotational symmetry can be calculated by dividing 360° by the order of rotational symmetry of the shape. For example, a square ha...
No shape can have rotational symmetry of order zero. The smallest order of rotational symmetry a shape can have is 1. This is because all shapes must look the same when rotated a full turn to their original position. A shape with no rotational symmetry has rotational symmetry order 1.
Examples of rotational symmetry in real life include windmills, wheels, fidget spinners, fan blades, ferris wheels and the recycling logo. Here is an example of a windmill fan showing rotational symmetry of order 3. Here is an example of a ferris wheel which looks the same whenever a new carriage reaches the top.
Examples of rotational symmetry in nature include flower petals, starfish, snowflakes and segments of fruit. These items will all look the same if rotated. Here is an example of rotational symmetry in nature. This plant has four leaves that all look the same. The order of rotational symmetry is 4. Here is an example of a snowflake with order of rot...

Jun 20, 2022 · Line symmetry is where we draw a line and every point on one side has a matching point on the other side. Different shapes can have differing lines of symmetry and can also have any number of them. The shape above has one line of symmetry, which is shown in the diagram, and no others.
