WEBLength of side of octagon = a = 10 cm. By the formula, we know, the length of the longest diagonal formula is given by: L = a√(4 + 2√2) Hence, L = 10√(4 + 2√2) L = 10 x √6.828. L= 10 x 2.613. L = 26.13 cm. Q.4: Find the area and perimeter of a regular octagon whose side is of length 2.5 cm. Solution: Given, Length of side of octagon ...
WEBAccording to the regular octagon definition, all its sides are of equal length. The perimeter of an octagon = 8 × (side). Here, the perimeter is given as 160 units. Thus, the length of each side = 160 ÷ 8 = 20 units. Therefore, the length …
WEBProperties. A regular octagon has: Interior Angles of 135°. Exterior Angles of 45°. Area = 2 (1+√2)s2, or approximately 4.828427 × s2 (where s=side length) Width w = (1+√2)s. Any octagon has: Sum of Interior Angles of 1080°. 20 diagonals. Geometry Index.
WEBProp. 10. Regularity. A regular octagon is a closed figure with sides of the same length and internal angles of the same size. It has eight lines of reflective symmetry and rotational symmetry of order 8. A regular octagon is represented by the Schläfli symbol {8}. The internal angle at each vertex of a regular octagon is 135 ° ( radians ).
WEBSides of a regular octagon are equal in length, and the opposite sides of a regular octagon are parallel . AB=BC=CD=DE=EF=FG=GH=AH and AB // EF, BC // FG, // GH, DE // AH. Irregular octagon. If not all of the sides and interior angles of an octagon are equal, it is an irregular octagon.

The Octagon - Definition, Geometry, and Types with Examples
WEBMay 29, 2023 · A polygon having eight sides and eight angles is referred to as an octagon in geometry. The term originates from the Greek word “oktágōnon,” with “oktá” meaning eight and “gōnia” meaning angle. There are various types of octagons, but the most common one is the regular Octagon, where all the sides and angles are equal.
WEBMar 1, 2024 · The tool can calculate the properties of the octagon, given either the length of its sides, or the inradius or the circumradius or the area or the height or the width. Enter below the shape dimensions.
