**What is the interior angle of a pentagon Answers.com**

The sum measures of interior angle is the addition of all interior angles of a polygon. In this article, we shall discuss about the sum measures of interior angles of a polygons. Also we shall see some examples to determine the sum measures of interior angles of polygons.... Interior angle: 140Â° Like any regular polygon, to find the interior angle we use the formula (180nâ€“360)/n . For a nonagon, n=9. See Interior Angles of a Polygon

**Sum of interior angles of a polygon Angles and**

Interior angle: 140Â° Like any regular polygon, to find the interior angle we use the formula (180nâ€“360)/n . For a nonagon, n=9. See Interior Angles of a Polygon...Add the number of sides of the polygon. The sum of all the degrees of the interior angles equals (n - 2)_180. This formula means subtract 2 from the number of sides and multiply by 180).

**Interior and Exterior Angles of Polygons (videos**

Place lines inside each of these polygons to show how they may be made up of just triangles. 5. Use the idea that the sum of the internal angles of a triangle is 180Â°, to find the sum of the how to learn manual transmission Another way to calculate the measure of angle 1 is to note that in a regular pentagon, each interior angle must have a measure of . Angle 1 is half of this, or 54Âº. The angle at point O is called a central angle since it has a vertex at the center of the regular pentagon.. How to find someone in las vegas

## How To Find The Interior Angle Of A Pentagon

### Example 3: Find the measure of each interior angle of a regular hexagon (Figure 3). Figure 3 An interior angle of a regular hexagon. Method 1: Because the polygon is regular, all interior angles are equal, so you only need to find the interior angle sum and divide by the number of angles.

- You may already know that triangles have 180Â° and quadrilaterals have 360Â°. However, do you know how many degrees are in a pentagon or a dodecagon? Let's take a look at some of the polygons to find a pattern. Notice that the number of triangles is 2 less than the number of sides in each example
- Another way to calculate the measure of angle 1 is to note that in a regular pentagon, each interior angle must have a measure of . Angle 1 is half of this, or 54Âº. The angle at point O is called a central angle since it has a vertex at the center of the regular pentagon.
- Add the number of sides of the polygon. The sum of all the degrees of the interior angles equals (n - 2)_180. This formula means subtract 2 from the number of sides and multiply by 180).
- The measurement of an interior angle of a pentagon depends on whether the pentagon is a "regular pentagon". The sum of the measures of the interior angles of any polygon can be calculated using the formula (n-2)180, where n = the number of sides.
