What regular polygon has 9 diagonals?
A regular octadecagon (an eighteen sided polygon) would have nine diagonals.
What sort of regular polygon has nine diagonals?
Hexagon
How do you calculate the measure of a central angle of a regular nine sided polygon?
To calculate the measure of a central angle of a regular nine-sided polygon, divide 360 degrees by the number of sides. In this case, divide 360 by 9. The measure of the central angle of a regular nine-sided polygon is 40 degrees.
Each exterior angle of a regular polygon is approximately 51.43 How many sides does the polygon have?
7 It is not possible for a regular polygon to have exterior angles of 180 degrees or less in plane geometry
What is a polygon with nine equal sides called?
It is a nonagon. It need not be a regular nonagon.
Calculate the measure of a central angle of a regular nine-sided polygon?
40
Is a nonagon symmetrical?
Any regular polygon of n sides, has an order of symmetry of n. Therefore, since a nonagon has nine sides, a nonagon has an order of symmetry of 9.
Calculate the measure of a central angle of a regular nine- sided polygon?
Each central angle of a regular 9 sided polygon: 360/9 = 40 degrees
What are the angles of a nine-sided polygon?
1260/9 ie 140 degrees assuming polygon is regular. Total is not affected by regularity.
What is the measure of one angle of a regular polygon with nine sides?
9-2.180=1260
What is the measure of one exterior angles of a regular polygon with nine sides?
It is: 40 degrees
What is a regular polygon called if one exterior angle equals 40 degrees?
A nine sided shape that is called a regular nonagon.
