How do you make a decagon shape?
Use the pentagon shape as an alternative method. Lightly draw and measure a regular pentagon. Lightly draw another identical pentagon directly over the original, rotated 180 degrees. Draw a line between each point of both pentagons to get a decagon shape.
What is a nonagon shape?
A nine sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners. The word nonagon comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.

How many lines of symmetry does nonagon have?
A regular nonagon has 9 lines of symmetry and a rotational symmetry of order 9, meaning that it can be rotated in such a way that it will look the same as the original shape 9 times in 360°. Nine 40° of rotation about the center.

What is the angle sum of a nonagon?
A nonagon has nine sides. Use the Polygon Interior Angles Sum Theorem to find the sum of its interior angle measures. = 7 ● 180 or 1260 Simplify. Answer: The sum of the measures is 1260.
What is the sum of the exterior angles of a nonagon?
The sum of the measures of the exterior angles is 360. A convex regular nonagon has 9 congruent exterior angles. 9n = 360 n = measure of each exterior angle n = 40 Divide each side by 9. The measure of each exterior angle is 40.

Here, a 3-sided polygon is a triangle, 4 sided polygon is a quadrilateral, 5-sided polygon is a pentagon, 6-sided polygon is a hexagon, 7-sided polygon is heptagon, 8-sided polygon is octagon, 9-sided polygon is called a nonagon and a 10-sided polygon is the decagon.
How many triangles does nonagon have?
Properties of all nonagons Number of diagonals 27 Number of triangles 7 Sum of interior angles 1260°.
What is the number of triangles in a nonagon?
A regular nonagon has up to 9 congruent triangles that do not overlap.
Is a nonagon concave or convex?
No line containing any of the sides will pass through the interior of the quadrilateral, so it is convex. Example 1a: There are 9 sides, so this is a nonagon. A line containing some of the sides will pass through the interior of the nonagon, so it is concave.
How many segments does a nonagon have?
A nonagon is also called enneagon, which is derived from a Greek word called enneagonon, which means nine corners. The first use of the word nonagon dates back to the early 17th century, and has a Latin prefix (nona) and a Greek suffix (gon), making it a polygon with nine sides and nine angles.
What is the value of one exterior angle of a nonagon?
Answer: The measure of an exterior angle of a regular nonagon is 40 degrees.

What is the formula for the area of a dodecagon?
The formula for finding the area of a regular dodecagon is: A = 3 × ( 2 + √3 ) × s2 , where A = the area of the dodecagon, s = the length of its side. For example, if the side of a regular dodecagon measures 8 units, the area of this dodecagon will be: A = 3 × ( 2 + √3 ) × s2 .
