## What regular polygon has an interior angle of 135?

octagon

What type of polygon is it? Summary: An interior angle of a regular polygon has a measure of 135°, it is an octagon.

### How many sides does a polygon have if its interior angle is 135?

8

Complete step-by-step answer: we have to find the number of sides of the polygon. Let’s start with the assumption that the number of sides be n, this means that we have n sided regular polygon whose interior angle is 135∘. Therefore, we get the number of sides that the polygon has as 8.

#### What is a regular polygon state the name of a regular polygon of 4 sides?

square

A regular polygon having 4 sides is known as square. Each interior angle is equal to 90∘. A regular polygon having 6 sides is known as a regular hexagon and its interior angle is equal to 120∘.

**What is the number of sides of a regular polygon that has an interior measure of 140?**

9

What is the name of a polygon whose interior angles are each 140°? Subtract both sides by 180°n. = 9. Therefore, the number of sides is 9 (nonagon).

**How many degrees is a Nonagon?**

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

540°

The General Rule

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

Quadrilateral | 4 | 360° |

Pentagon | 5 | 540° |

Hexagon | 6 | 720° |

Heptagon (or Septagon) | 7 | 900° |

### What is a regular polygon state?

A polygon is said to be a regular polygon, if all its. (i) interior angles are equal; (ii) sides are equal; and. (iii) exterior angles are equal.

#### What is irregular polygon class 8?

Irregular polygons are polygons that have unequal angles and unequal sides, as opposed to regular polygons which are polygons that have equal sides and equal angles. A scalene triangle is a triangle in which all the three sides are in different lengths, and all the three angles are of various measures.

**What is the measure of each angle in a regular polygon with 4 sides?**

90°

The General Rule

If it is a Regular Polygon (all sides are equal, all angles are equal) | ||

Shape | Sides | Each Angle |
---|---|---|

Triangle | 3 | 60° |

Quadrilateral | 4 | 90° |

Pentagon | 5 | 108° |

**How many degrees is a Nanagon?**

1260°

## What is a regular polygon?

We know that a regular polygon is a polygon that has all sides of equal length and all interior angles of equal measure. In this lesson we’ll learn how to construct them using compass and a ruler.

### How to change the length of the side of a regular polygon?

Try thisAdjust the regular polygon below by dragging any orange dot, or alter the number of sides. The length of the sides will change. The formulas below give the length of the side of regularpolygon given the number of sides and either the radius or apothem. Side length given the apothem (inradius)

#### How do you find the interior angles of a regular polygon?

Formulas of Regular Polygon. The formula to find the sum of interior angles of a regular polygon when the value of n is given. The sum of an interior angle = (n-2) x 180⁰. Where n is the number of sides of the polygon. The formula to calculate each interior angle of a regular polygon. Interior angle = \\[\\frac{(n-2)\imes180^{o}}{n}\\]

**Which base units can be substituted for regular polygon?**

Any other base unit can be substituted. A regular polygon is a polygon that is both equiangular and equilateral. All sides are equal length placed around a common center so that all angles between sides are also equal. When the number of sides, n, is equal to 3 it is an equilateral triangle and when n = 4 is is a square.
