9 sided shape name4/28/2024 ![]() Nonagons can be convex or concave, and they can appear in different shapes depending on their angle measurements. It has nine interior angles and nine sides that are all the same length. � What is the definition of nonagon in geometry?Ī nonagon, also known as an enneagon, is a nine-sided polygon in Euclidean geometry. Understanding how these shape works are essential for students looking to develop their knowledge in math-related fields so they may apply what they learn later on in their studies. In conclusion, a nonagon is an important geometric shape with many applications across multiple disciplines of mathematics including trigonometry, calculus, and coordinate geometry � just to name a few! It has nine interior angles that all add up to 1260 degrees and its sides always have equal lengths regardless if it's convex or concave. ![]() In addition, they can also help students understand basic concepts like symmetry, transformations, congruency, similarity, lines/segments/rays, etc. Nonagons can also be found in other areas such as trigonometry and calculus as well as more advanced topics like coordinate geometry or graph theory. Similarly, when calculating its perimeter you must find out how long each side is and then add them together to get its total perimeter size.�� For example, when calculating the area of a nonagon you must calculate the area of each triangle inside the shape and then add them together to get the total area of the nonagon itself. They are often used when solving problems related to area and perimeter. Nonagons are used in various areas of geometry. As previously mentioned, it can be either convex or concave depending on which type of angles it has if the angles are all acute, then the nonagon will be convex if any one of them is obtuse or right-angled, then it will be concave.� These angle measurements mean that two adjacent sides meet at an obtuse angle (140�), while the remaining seven sides meet at an acute angle (70�). Let�s take a look at the properties of a nonagon and how they are used in geometry.�Ī nonagon�s nine interior angles all add up to 1260�, and each individual angle measures 140�.
