Webb23 okt. 2024 · Any shape with five corners or five sides is called a pentagon . Pentagons are 2D shapes that have 5 corners and 5 sides such as any of the shapes in the image above. The shape in the middle of the image is a regular pentagon because it has 5 sides that are all the same length. WebbNot all sides and angles are equal. Octagons and other polygons can also be classified as either convex or concave. If all interior angles of an octagon or polygon are less than 180°, it is convex. If one or more …

The perimeter of a pentagon is the distance around … Webb3 nov. 2024 · The above interior angle formula is derived by dividing a polygon into triangles, and this number can be found with the calculation: n - 2. In this formula, n is equal to the number of sides of the polygon. A hexagon (six sides) can be divided into four triangles (6 - 2) and a dodecagon into 10 triangles (12 - 2). WebbA sector of a circle is essentially a proportion of the circle that is enclosed by two radii and an arc. Given a radius and an angle, the area of a sector can be calculated by multiplying the area of the entire circle by a ratio of the known angle to 360° or 2π radians, as shown in the following equation: area =. θ. 360. darken white scars
