What polygon has an interior angle of 120?

What polygon has an interior angle of 120?

Answer: If an interior angle of a regular polygon measures 120°, it has 6 sides (Hexagon).

What is one interior angle of a pentagon?

108 degrees
The measure of one interior angle of a regular pentagon is 108 degrees.

What regular polygon has an exterior angle of 120 degrees?

equilateral triangle
Each exterior angle of an equilateral triangle is 120 degrees and hence this the maximum possible value of the exterior angle of a regular polygon.

What is a 120 sided polygon?

In geometry, a 120-gon is a polygon with 120 sides. The sum of any 120-gon’s interior angles is 21240 degrees. Alternative names include dodecacontagon and hecatonicosagon.

Is it possible for a regular polygon whose interior angle measures 130?

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.

How do you find the measure of one interior angle of a pentagon?

1 Answer

  1. To find the measure of one interior angle, first substitute n as 5 :
  2. Since a pentagon has 5 interior angles, divide the sum of interior angles ( 540∘ ) by 5 :
  3. ∴ , the measure of one interior angle is 108∘ .

What is the interior angle of Nonagon?

140°
Nonagon/Internal angle

How many angles are in a regular pentagon?

Hence, the number of angles in a pentagon are five (in any polygon the number of sides is equal to the number of angles). Below are the different types of polygons namely regular, irregular, and concave pentagon, respectively. Regular pentagon is also called convex pentagon.

What are the different types of Pentagon polygons?

Below are the different types of polygons namely regular, irregular, and concave pentagon, respectively. Regular pentagon is also called convex pentagon. Sum of the interior angles of a polygon of n sides = (n – 2) × 180° = 540°.

What do you need to know about the Pentagon?

You should know: 1 That a pentagon is a five-sided polygon with five angles 2 The identifying properties of a pentagon 3 The different types of pentagons

Which is an example of a concave Pentagon?

Concave pentagon – One interior angle that is greater 180° 180 ° A common example of a convex irregular pentagon is the home plate on a baseball field. All pentagons (regular and irregular) are five-sided shapes, with five interior angles and five exterior angles.
