How many lines of symmetry does a nonagon have?
9Nonagon / Line of symmetry
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 are the 9 sides of a nonagon?
The given nonagon ABCDEFGHI has sides AB, BC, CD, DE, EF, FG, GH, HI, and IA and angles ∠A, ∠B, ∠C, ∠D, ∠E, ∠F, ∠G, ∠H, and ∠I.
What is the sum of exterior angles of a nonagon?
360
At each vertex, extend a side to form one exterior angle. 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.

How many sides does a Apeirogon have?
In geometry, an apeirogon (from the Greek words “ἄπειρος” apeiros: “infinite, boundless”, and “γωνία” gonia: “angle”) or infinite polygon is a generalized polygon with a countably infinite number of sides. Apeirogons are the two-dimensional case of infinite polytopes….Apeirogon.

How many angles does a nonagon have?
nine angles
To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)… And there are nine angles… So, the measure of the angle of a regular nonagon is 140 degrees.
