Download Sum Of All Interior Angles Of A Nonagon Pics. A polygon is a plane shape bounded by a finite chain of straight lines. That is as far as you can go with the information given.

So, to calculate the sum of interior angles in a polygon, you have to multiply the number of triangles in the polygon by 180°. To find the measure of the central angle of a regular heptagon, make a circle in the middle. Equation for sum of interior angles of a polygon.

Each time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total nonagon.

How many sides does the polygon have ? Each interior angle of a regular polygon measures 160°. Divide that by seven angles. Equation for sum of interior angles of a polygon.

You can convince on the example of a triangle, square, pentagon etc that the sum of the interior angles of all triangles equals the sum.

To find the sum of the interior angles of a nonagon, divide it up into triangles.

That will give you the missing angle.

And also if i divide it into 9 triangles angles with each side equal to the radius of circumcircle.
