## Is it possible to have a regular polygon whose interior angle is 45 degree?

Answer. No it is not possible to have a regular polygon each of whose interior angle is 45°.

## Is it possible for a regular polygon to have an interior angle measure of 130 explain?

The sum of the exterior angles is always 360° and we can use this fact to find the number of sides. The number of sides has to be a natural number, so 7.2 is not possible, therefore 130° is not possible for the angles of a regular polygon.

## Is it possible for a regular polygon to have an interior angle of 72?

A regular polygon has equal exterior angles of 72°. (a) Calculate the size of each interior angle in the regular polygon. We do this by subtracting the exterior angle of 72° from 180°. The answer is 180° – 72° = 108°….Question 2.

(a) a regular decagon | exterior = ° |
---|---|

(b) a regular pentagon | exterior = ° |

interior = ° |

## Why can’t 173 degrees have interior angles?

If you enter 173 degrees, you don’t get an integer for the number of sides because there is no such polygon.

## How many sides does a regular polygon have if each interior angle has a measure of 172 degrees?

Each exterior angle = 180 – 172 = 8 degrees. = 45 sides.

## What is the interior angle of a regular polygon with 18 sides?

Regular Polygons

Sides | Name | Interior Angles |
---|---|---|

17 | Heptdecagon | 158.82° |

18 | Octdecagon | 160.00° |

19 | Enneadecagon | 161.05° |

20 | Icosagon | 162.00° |

## What is the sum of 4 of the interior angles of a regular pentagon?

The General Rule

Shape | Sides | Sum of Interior Angles |
---|---|---|

Quadrilateral | 4 | 360° |

Pentagon | 5 | 540° |

Hexagon | 6 | 720° |

Heptagon (or Septagon) | 7 | 900° |
