WebTwo equiangular octagons, one regular, one not: If a quadrilateral is equiangular, it is a rectangle. Mathematical background In the case of triangles, being equiangular requires that the triangle also be equilateral. That is, every equiangular triangle is a regular triangle. However, this is not the case for all polygons. WebAn octagon is an 8-sided polygon (a flat shape with straight sides). First, have a play with an octagon: Regular or Irregular When all angles are equal and all sides are equal it is regular, otherwise it is irregular Concave or Convex A convex octagon has no angles pointing …

WebNov 3, 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). WebOctagon: 8 Sides Octagons have eight sides. A regular octagon is a shape consisting of eight even sides in which the interior angles add up to 1080 degrees.
