How many sides does 9 octagon have?
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon, t{8} is a hexadecagon, {16}.
Is an octagon 8 equal sides?
The octagon having eight congruent sides and angles is known as a regular octagon. Every regular octagon has the same angle measures. All sides are equal in length, and all the angles are equal in measure. The interior angles add up to 1080°(135×8) and the exterior angles add up to 360°.
Does octagon have 8 equal sides or just 8 sides?
An 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
Do all octagons have 8 sides?
Properties of Octagon These have eight sides and eight angles. All the sides and all the angles are equal, respectively. There is a total of 20 diagonals in a regular octagon. The total sum of the interior angles is 1080°, where each angle is equal to 135° (135×8 = 1080) Sum of all the exterior angles of the octagon is 360°, and each angle is 45° (45×8=360).
Does Octagon need to have equal sides and angles?
If all the sides and interior angles of an octagon are equal, it is a regular octagon. Otherwise it is an irregular octagon. 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.
Is an eight sided figure called an octagon?
An 8-sided shape is called an octagon. Any time that a shape is a polygon, and it has eight sides, we call it an octagon. Similarly, you may ask, is an octagon any shape with 8 sides?
