WebAll sides and interior angles are equal. Not all sides and angles are equal. Nonagons and other polygons can also be classified as either convex or concave. If all interior angles of a nonagon are less than 180°, it is convex. If one or more interior angles is larger than 180°, it is concave. A regular nonagon is a convex nonagon. Convex nonagon.

Next, observe that the base is a septagon with 7 edges. Then, use the formula to calculate the number of faces in the figure. n + 1 = number of faces in a pyramid 7 + 1 = 8 f a c e s.
Web11 apr. 2024 · 4. Given two angles and the side between them (ASA) Triangle Area = a² × sin(β) × sin(γ) / (2 × sin(β + γ)) There is a special type of triangle, the right triangle. In that case, the base and the height are the two sides that form the right angle. Then, the area of a right triangle may be expressed as: Right Triangle Area = a × b / 2 WebA 12 sided shape is a polygon called a dodecagon. Basically, a dodecagon is a polygon made up of 12 sides, 12 angles, and 12 vertices.
