## What letters of the alphabet have rotational symmetry?

Capital letters that have rotational symmetry are: Z, S, H, N and O.

**Does a pentagon have 72 degree rotational symmetry?**

A regular polygon has rotational symmetry by turning any multiple of the central angle. The central angle is 360 degrees divided by the number of sides. As an example: A pentagon has five sides, 360/5 =72. So a rotation of 72, 144, 216, 288, 360, 432, …

**How many rotational symmetry does alphabet Z have?**

Answer:

English Alphabet Letter | Line Symmetry | Order of Rotational Symmetry |
---|---|---|

Z | No | 2 |

S | No | 2 |

H | Yes | 2 |

O | Yes | Infinite |

### How do you find the degree of rotational symmetry?

To find the degree of rotation, you would divide 360 degrees by the order. Since 2 is the smallest order possible, then 180 is the largest degree of rotation possible.

**How many order of rotational symmetry does letter I have?**

2

Lines of symmetry in Alphabets

Alphabet letters | Line symmetry | Number of lines of symmetry |

F | No | 0 |

G | No | 0 |

H | Yes | 2 |

I | Yes | 2 |

**What letters have rotational symmetry but not line symmetry?**

N and S have rotational symmetry, but they don’t have any line symmetry. An interesting letter is O because it looks almost, but not quite like a circle.

#### What rotational symmetries does a regular pentagon have?

Therefore the order of rotational symmetry of a regular pentagon is 5.

**Is a pentagon rotational symmetry?**

Order 5Pentagon / Rotational symmetry

**Does O have rotational symmetry?**

The alphabets Z, H, S, N and O have rotational symmetry.

## How many symmetry lines does N have?

Lines of symmetry in Alphabets

**Does a triangle have rotational symmetry of 180?**

An equilateral triangle has rotational symmetry order 3. A square has rotational symmetry of order 4. A regular pentagon has rotational symmetry of order 5….

Shape | Order of Rotational Symmetry | Angle of Rotational Symmetry |
---|---|---|

Equilateral Triangle | 3 | 120° |

Rectangle | 2 | 180° |

Square | 4 | 90° |

Parallelogram | 2 | 180° |

**How do you know if a figure has rotational symmetry?**

A shape has rotational symmetry when it can be rotated and it still looks the same. The order of rotational symmetry of a shape is the number of times it can be rotated around a full circle and still look the same.

### Which geometric figure has 72 degree rotational symmetry?

SOLUTION: which geometric figure has 72 degree rotational symmetry .. Rhombus.. Regular pentagon.. Equlateral triangle.. Square? Question 48301: which geometric figure has 72 degree rotational symmetry .. Rhombus.. Regular pentagon.. Equlateral triangle.. Square? You can put this solution on YOUR website!

**What is the Order of rotational symmetry of the letters?**

This triangle matches up 3 times and so, the order of rotational symmetry is 3. 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.

**What is the angle of rotation for rotational symmetry?**

Angle of Rotational Symmetry For a figure or object that has rotational symmetry, the angle of turning during rotation is called the angle of rotation. Example: when a square is rotated by 90 degrees, it appears the same after rotation. So, the angle of rotation for a square is 90 degrees.

#### What is the Order of rotational symmetry for a decagon?

Without drawing it, can you say what the Order of rotational symmetry is for a regular decagon, a 10-sided polygon? It is Order 10, meaning you can rotate the figure 36° and match it to the original. You can do that 10 times in making one complete rotation.
